Influenza viruses have developed ways to evade the body's immune response using an antigenic variation known as antigenic shift (replacement of HA and NA antigens with novel subtypes from noninfluenza viruses) and drift (mutations within antibody-binding sites in HA and or NA). Because of new ...
antibody and the p24 antigen, and the fifth generation additionally differentiates between antibody and antigen allowing assessing the acuteness of the infection and also differentiates between HIV-1 and HIV-2. Both of these new assays decrease the window period almost to the extent of molecular ...
Antibody responses following HCMV infection of huBLT mice were assessed by enzyme-linked immunosorbent assay (ELISA). Costar clear polystyrene high-protein-binding enzyme immunoassay (EIA) plates (Corning) were coated in either purified HCMV virion preparations (5 ug/mL) diluted in PBS or recomb...

The sample antigen competes with a reference antigen for binding to a specific labelled antibody. The reference antigen is pre-coated on a multi-well plate. The sample is pre-incubated with labelled antibody and added to the wells. Depending on the amount of antigen in the sample, the free ...

The West Nile virus (WNV) nonstructural protein 1 (NS1) is an important antigenic protein that elicits protective antibody responses in animals and can be used for the serological diagnosis of WNV infection. Although previous work has demonstrated the vital role of WNV NS1-specific antibody response...
