Parainfluenza Ab Dot Assay Kits

Parainfluenza IgM and IgG Dot assay test kits are rapid immuno filtration reagent kits, used to help the diagnosis of Parainfluenza infection.

Parainfluenza IgM Dot Assay Kit

Intended Use

Parainfluenza IgM and IgG Dot assay test kits are rapid immuno filtration reagent kits, in which monoclonal parainfluenza antigens are used as capturer, and anti-human antibodies as detector based indirect assay principle. These parainfluenza serum test kits are used to respectively detect IgM and IgG antibodies specific to human parainfluenza virus (HPIV) in the serum specimen, and these parainfluenza serum test kits are used to help the diagnosis of Parainfluenza infection.

Usually, infection with parainfluenza virus can be confirmed by demonstration of a significant rise in the IgG antibody between appropriately collected serum specimens from the same patient, or the high concentration of specific IgM antibody in one single serum specimen.

Parainfluenza

Human parainfluenza virus (HPIV) is an enveloped single-stranded RNA virus, which can infect both the lower and upper respiratory tracts of human beings. The parainfluenza virus is the second most common cause of lower respiratory tract infection in younger children; the infection is most severe in infants and become less severe within the groups with higher age. Infections are most common in fall and winter. Similar to RSV, the first cause of respiratory tract infection in children, parainfluenza can cause repeated infections throughout life.

Specimen

Serum Collection

Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.

Allow the blood to clot, or separate the serum by centrifugation.

Carefully withdraw the serum into a new pre-labeled tube.

serum Storage Condition

Test specimens as soon as possible after collecting. The specimens can be stored up to 5 days at 2-8°C if not tested immediately. The specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times. Prior to testing, bring frozen specimens to room temperature slowly and mix gently. 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 DGFIA Capture

DGFIA Capture Method Illustration

For the detection of IgM-class antibodies, capture technique has its advantage in that it can reduce the interference from the IgG class, thus increase the specificity of the test kit.

In a capture dot filtration test kit, antibodies directed to human IgM antibody (anti-i chain) are pre-coated in the test region on the millipore filtering membrane. When specimen is added, the IgM, if present, will be captured by this secondary antibody, anti-IgM.

After washing away the specimen, especially the IgG antibody, the antigen conjugated with colloidal gold particle will be added. If the IgM antibody was captured in the prior step, the IgM will bind to the antigen conjugate. When the colloidal gold particles congregate, a red or pink color will develop, indicating a positive result.

If no IgM in the specimen, this complex will not develop, the antigen conjugated colloidal gold particles will not congregate, and no color will develop in the test region, indicating a negative result.

Testing Principle of DGFIA indirect

DGFIA Indirect Method Illustration

With indirect Dot filtration test kit, the millipore filtering membrane is pre-coated with purified or recombinant viral antigens. The detecting conjugate reagent is stored in a vial, whose main component is rabbit anti human IgG (anti-IgG) antibodies, which is conjugated with colloidal gold particles.

During the first step, sample is added to the sample well in the test cassette. The target IgG antibodies, if present, will be captured by the pre-coated antigens.

The wells are washed to remove unbound serum proteins. Then, the colloidal gold conjugate is added. If the target IgG antibodies have been captured in the first step, the IgG antibody will react with the added secondary antibody, anti-IgG conjugate, and red color will develop, indicating a positive result.
