EBV EA (Early Antigen) IgA ELISA Kit

  • Created on the 18 July, 2017.

BACKGROUND

Epstein–Barr virus (EBV) can also be known as human herpesvirus 4 (HHV-4), it belongs to the herpes family of viruses that is very common in humans. The infection with EBV is usually either through genital secretion or by the oral transfer of saliva. EBV-associated infection have in many cases been linked to a high risk of many autoimmune diseases for example systemic lupus erythematosus, dermatomyositis, rheumatoid arthritis, multiple sclerosis and Sjögren’s syndrome. EBV EA appears to be associated to the acute phase of the illness and in most cases drops to undetectable levels after 3-6 months. However, the detection of early antigen (EA) is a good indicator of an active infection. Diagnosing EBV infection are often difficult and challenging due to the fact that the symptoms are very similar to many other illnesses. Blood test and many other laboratory methods (for example ELISA assays) can be helpful to distinguish whether one is susceptible to EBV infection or has had a recent or even a past infection.

INTENDED USE

Human EBV EA-IgA ELISA kit can be used for detecting in-vitro quantitative amounts of human IgA antibodies against Epstein–Barr virus early antigen (EBV EA) using serum or plasma samples. This assay has a minimum analytical sensitivity limit of 1.1 U/ml.

SENSITIVITY

The minimum detection sensitivity level of human Epstein–Barr virus early antigen (EBV EA) IgA using this human EBV EA-IgA ELISA kit was 1.1 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.
