HBsAg ELISA Kit

HBV ELISA Test Kits

Atlas Link Technology Co., Ltd supplies various ELISA kits for the detection of Hepatitis-B infection, as shown below in the HBV ELISA product table, mainly including HBsAg ELISA, HBsAb ELSIA, HBeAg ELISA, HBeAb ELISA, and HBcAb ELISA kits. All these HBV ELISA kits are enzyme-linked immunosorbent assay, for qualitative detection of Hepatitis related antigens or antibodies in human serum or plasma.

It is intended for screening of blood donors in blood banks, and are also used as several diagnostic test kits for clinical diagnosis and management of the Hepatits-B disease.

HBsAg Early Detection

Hepatitis B surface antigen or HBsAg, previously described as Australia antigen, is the most important protein of the envelope of Hepatitis B Virus. HBsAg can be detected 2 to 4 weeks before the ALT levels become abnormal, and 3 to 5 weeks before symptoms develop. The serological detection of HBsAg is a powerful method for the diagnosis and prevention of HBV infection and ELISA has become an extensively used analytical system for screening of blood donors and clinical diagnosis of HBV in infected individuals.

When used in conjunction with tests for other HBV serological markers, a laboratory diagnosis or a rule out of HBV infection can be achieved.

HBV and Hepatitis-B Disease

Hepatitis B virus (HBV) is an enveloped, double-stranded DNA virus belonging to the Hepadnaviridae family and is recognized as the major cause of blood transmitted hepatitis together with hepatitis C virus (HCV); also hepatitis-B can be transmitted via sexual contact. Infection with HBV induces a spectrum of clinical manifestations ranging from mild, inapparent disease to fulminant hepatitis, severe chronic liver diseases, which in some cases can lead to cirrhosis and carcinoma of the liver.

Several serological markers are commonly used in the immuno detection of Hepatitis-B infection, including HBsAg, HBsAb, HBeAg, HBeAb, HBcAb and HBc IgM antibody.

Testing Principle of Double Antibody Sandwich ELISA

ELISA Double Antibody Sandwich Method Illustration

With this type of ELISA test kits, the detection target usually is hormone protein or viral antigen.

In the test kit, monoclonal or polyclonal antibodies specific to the target protein or antigen are used as capturer, which are pre-coated on the polystyrene microwell strips. The sample from the patient, such like urine, serum or plasma sample is added to the microwells. And a second antibody conjugated with horseradish peroxidase (HRP) is used as the detector, which then is added to the microwells. Usually, the samples and the second antibody conjugate are added to the microwell in the same time, thus it is a one-step assay process.

During incubation, the specific immuno-complex formed in case of presence of the target antigen or protein in the sample, and is captured on the solid phase.

After washing to remove sample serum proteins and unbound HRP-conjugate, Chromogen solutions containing tetramethyl benzidine (TMB) and urea peroxide are added to the wells. In presence of the antibody-antigen-antibody (HRP) "sandwich" immuno complex, the colorless Chromogens are hydrolyzed by the bounded HRP-conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a positive result. The amount of color can be measured and is proportional to the amount of antigen or protein in the sample.

Wells containing samples negative for the target antigen or protein remain colorless.

Testing Principle of Double Antigen Sandwich ELISA

ELISA Double Antigen Sandwich Method Illustration

In double antigen sandwich ELISA kit, a recombinant or purified antigen is pre-coated on the polystyrene microwell strips, which acts as the capturer. And, a second antigen conjugated to tracer enzyme -horseradish peroxidase (HRP) is used as the detector. Depending on whether the specimen is added together with the HRP conjugate into the microwell or not, double antigen sandwich ELSIA are subdivided to one-step kit and two-step kit.

In one step kit, the sample is incubated in the microwells together with the second antigen HRP conjugate. In case of presence of the target antibody in the sample, the pre-coated and conjugated antigens will be bound to the two variable domains of the antibody during incubation, thus the specific antigen-antibody-antigen-HRP immuno complex will develop and be captured on the solid phase.

After washing to remove unbound sample and conjugates, Chromogen solutions containing tetramethyl benzidine (TMB) and urea peroxide are added to the wells and in presence of the "sandwich" immuno complex, the colorless Chromogens are hydrolyzed by the bound HRP conjugate to a blue colored product, which turns yellow after stopping the reaction with sulfuric acid, indicating a positive result. The amount of color can be measured and is proportional to the amount of antibody in the sample.

Wells containing samples negative for target antibody remain colorless.

For two-step kit, the antibodies in the sample are first allowed to react with the pre-coated antigens during the first incubation. During this process, the target antibodies, if present, will be captured on the polystyrene microwell strips. In turn, they are detected by the addition of the HRP-conjugated antigens, with the same color development as described for one-step kit.

Testing Principle of Competitive Binding ELISA

ELISA Competitive Method Illustration

ELISA kit based on competitive principle is one-step test kit, in which a fixed amount of purified viral specific antigens is pre-coated in the microwell strips.

During the testing process, the sample and monoclonal antibodies conjugated to horseradish peroxidase (HRP) is added to the microwells together. During incubation, the target antibodies, if present in the sample, compete with the HRP conjugated antibodies to bind to the pre-coated antigens. When no target antibodies present in the sample, the HRP labeled antibodies will bind with the antigens inside the wells and any unbound HRP-Conjugate is removed during washing.

Chromogen A and B solutions are added into the wells and during the second incubation, the colorless Chromogens are hydrolyzed by the bound HRP-Conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a NEGATIVE result.

No or low color developing suggests the presence of the target antibodies in the sample. So the color developed on the microwell strips is negatively related to the concentration of the target antibodies.

Testing Principle of Capture ELISA

ELISA Capture Method Illustration

For the detection of IgM-class antibodies, in order to avoid the interference from the IgG class, a solid phase, two-step incubation, antibody capture assays is usually used.

In capture ELISA kit, polystyrene microwell strips are pre-coated with antibodies directed to human IgM (anti-i chain). The patient’s serum/plasma sample is added, and during the first incubation, any IgM antibodies will be captured in the wells, and IgG antibodies on the other hand will not.

After washing out all other components of the sample and in particular IgG antibodies, the target IgM antibodies captured on the solid phase are detected by the addition of viral antigens conjugated to horseradish peroxidase (HRP). During the second incubation, the conjugated antigens will specifically react with the viral specific IgM antibodies.

After washing to remove unbound conjugates, Chromogen solutions are added to the wells. During the third incubation, the colorless chromogens are hydrolyzed by the bound HRP conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a positive result; the amount of color can be measured and is proportional to the amount of antibody in the sample.

Wells containing samples negative for the target IgM antibodies remain colorless, indicating negative result.

Specimens containing visible particulate matter should be clarified by centrifugation before testing. Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.

Testing Principle of Capture ELISA

ELISA Capture Method Illustration

For the detection of IgM-class antibodies, in order to avoid the interference from the IgG class, a solid phase, two-step incubation, antibody capture assays is usually used.

In capture ELISA kit, polystyrene microwell strips are pre-coated with antibodies directed to human IgM (anti-i chain). The patient’s serum/plasma sample is added, and during the first incubation, any IgM antibodies will be captured in the wells, and IgG antibodies on the other hand will not.

After washing out all other components of the sample and in particular IgG antibodies, the target IgM antibodies captured on the solid phase are detected by the addition of viral antigens conjugated to horseradish peroxidase (HRP). During the second incubation, the conjugated antigens will specifically react with the viral specific IgM antibodies.

After washing to remove unbound conjugates, Chromogen solutions are added to the wells. During the third incubation, the colorless chromogens are hydrolyzed by the bound HRP conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a positive result; the amount of color can be measured and is proportional to the amount of antibody in the sample.

Wells containing samples negative for the target IgM antibodies remain colorless, indicating negative result.

Testing Principle of Double Antibody Sandwich ELISA

ELISA Double Antibody Sandwich Method Illustration

With this type of ELISA test kits, the detection target usually is hormone protein or viral antigen.

In the test kit, monoclonal or polyclonal antibodies specific to the target protein or antigen are used as capturer, which are pre-coated on the polystyrene microwell strips. The sample from the patient, such like urine, serum or plasma sample is added to the microwells. And a second antibody conjugated with horseradish peroxidase (HRP) is used as the detector, which then is added to the microwells. Usually, the samples and the second antibody conjugate are added to the microwell in the same time, thus it is a one-step assay process.

During incubation, the specific immuno-complex formed in case of presence of the target antigen or protein in the sample, and is captured on the solid phase.

After washing to remove sample serum proteins and unbound HRP-conjugate, Chromogen solutions containing tetramethyl benzidine (TMB) and urea peroxide are added to the wells. In presence of the antibody-antigen-antibody (HRP) "sandwich" immuno complex, the colorless Chromogens are hydrolyzed by the bounded HRP-conjugate to a blue colored product. The blue color turns yellow after stopping the reaction with sulfuric acid, indicating a positive result. The amount of color can be measured and is proportional to the amount of antigen or protein in the sample.

Wells containing samples negative for the target antigen or protein remain colorless.
