HSV 1 IgG Torch ELISA Test Kit

Intended use

The HSV1 IgG assay is an enzyme-linked immunosorbent assay (ELISA) for the in vitro quantitative determination of IgG antibodies to Herpes simplex virus 1 (HSV1) in Human serum and plasma.

Summary

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans.Both HSV-1 (which produces most cold sores) and HSV-2 (which produces most genital herpes) are very common and contagious. They can be spread when an infected person begins shedding the virus. About 67% of the world population under the age of 50 has HSV-1. In the United States more than one-in-six people have HSV-2. Although it can be transmitted through any intimate contact, it is one of the most common sexually transmitted infections. HSV evades the immune system through interference with MHC class I antigen presentation on the cell surface, by blocking the transporter associated with antigen processing (TAP) induced by the secretion of ICP-47 by HSV.In the host cell, TAP transports digested viral antigen epitope peptides from the cytosol to the endoplasmic reticulum, allowing these epitopes to be combined with MHC class I molecules and presented on the surface of the cell. Viral epitope presentation with MHC class I is a requirement for activation of cytotoxic T lymphocytes (CTLs), the major effectors of the cell-mediated immune response against virally-infected cells. ICP-47 prevents initiation of a CTL-response against HSV, allowing the virus to survive for a protracted period in the host.

Test principle

Indirect method. Total duration of assay: 70 minutes Polystyrene microwell strips pre-coated with recombinant HSV-1 antigens expressed in insect cells. Patient’s serum or plasma sample is added, and during the first incubation step, the specific HSV-1 IgG antibodies will be captured inside the wells if present. The microwells are then washed to remove unbound serum proteins. A second set of Mouse Anti-Human IgG antibody conjugated to the enzyme Horseradish Peroxidase (HRP-Conjugate) and expressing the same epitopes as the pre-coated antigens is added, and during the second incubation, they will bind to the captured antibody. The microwells are washed to remove unbound conjugate, and Chromogen solutions are added into the wells. In wells containing the antigen-antibody-anti- IgG(HRP) immunocomplex, the colorless Chromogens are hydrolyzed by the bound HRP conjugate to a blue colored product. The blue color turns yellow after the reaction is stopped with sulfuric acid. The amount of color intensity can be measured and it is proportional to the amount of antibody captured in the wells, and to the sample respectively. Wells containing samples negative for HSV-1 IgG remain colorless.

Technical Parameters:

Specimen collection and preparation

• Human serum or plasma is recommended for this assay.

• Cap and store the samples at 18-25 ℃ for no more than 8 hours. Stable for 7 days at 2-8℃, and 1 month at -20℃. Freeze only once.

• Do not use heat-inactivated samples.

• Sediments and suspended solids in samples may interfere with the test result which should be removed by centrifugation. Ensure that complete clot formation in serum samples has taken place prior to centrifugation.

• Avoid grossly hemolytic, lipemic or turbid samples.
