EBV VCA IgG ELISA Kit

  • Created on the 18 July, 2017.

BACKGROUND

Epstein–Barr virus viral-capsid antigen (EBV-VCA) is responsible for the viral capsid of the Epstein–Barr virus and the antigen itself is the target of anti-VCA antibodies. These anti-VCA antibodies play an important role in diagnosing infectious mononucleosis. The identification of high levels of anti-VCA IgM can be used to confirm acute infection, whereas high levels of anti-VCA IgG antibodies indicates prior infection. Anti-VCA IgM is found to appear during the early stages of EBV infection and is gone between 4-6 weeks, whereas anti-VCA IgG is only present during acute phase infection and it peaks at 2-4 weeks and persists throughout the lifetime.

INTENDED USE

Human EBV VCA-IgG ELISA kit is a method designed for measuring in-vitro quantitative levels of human IgG antibodies against Epstein–Barr virus viral-capsid antigen (EBV VCA) in plasma or serum samples. This assay has a minimum analytical sensitivity limit of 1.29 U/ml.

SENSITIVITY

The minimum detection sensitivity level of human Epstein–Barr virus viral-capsid antigen (EBV VCA) IgG using this human EBV VCA IgG ELISA kit was 1.29 U/ml. The dynamic assay range for this kit is 1.0 – 200.0 U/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
