HBeAg ELISA Kit

 

Catalog No.:BE103A

 

Enzyme-linked immunosorbent assay for the detection HBeAg in serum or plasma

INTENDED USE

 

HBeAg EIA is a qualitative enzyme immunoassay for the detection of HBeAg in human serum or plasma.

 

SUMMARY AND PRINCIPLE OF THE TEST

 

The Hepatitis B e antigen is found to be related to Hepatitis B viral infection. HBeAg is usually found in the early phase of Hepatitis B viral infection. The titer of HBeAg rises rapidly during the period of virus replication. The presence of HBeAg correlates with increasing numbers of infectious viruses (Dane particles) and the presence of viral specific DNA polymerase in serum. During the HBeAg positive stage, hepatitis B patients are at increasing risk of transmitting the virus to their contacts. Persistent presence of HBeAg in the hepatitis B virus carrier is often associated with chronic active hepatitis.

 

The HBeAg EIA is a sandwich immunoassay, which employs monoclonal and polyclonal antibodies specific for HBeAg. Microtiter wells are coated with monoclonal antibodies specific for HBeAg. A serum specimen is added to the antibody coated microtiter wells together with enzyme conjugated polyclonal antibodies. HBeAg, if present, will form an antibody-HBeAg-antibody-enzyme complex. The plate is then washed to remove unbound materials. Finally, a solution of substrate is added to the wells and incubated. A blue color will develop in proportion to the amount of HBeAg present in the specimen. The enzyme substrate reaction can be stopped and the result is visualized by the naked eye or obtained by EIA plate reader for absorbance at wavelength of 450 nm (450 nm/630 nm).

SPECIMEN COLLECTION AND PREPARATION

 

Serum should be prepared from a whole blood specimen obtained by acceptable medical techniques. Either serum or plasma can be used in this test.  Remove serum or plasma from the clot or blood cells as soon as possible to avoid hemolysis.  Specimen with extensive particulate should be clarified by centrifugation prior to use.  Specimen frozen at -20°C or colder may be used.  Avoid repeated freeze thaw.

 

STORAGE OF TEST KIT

 

Unopened test kits should be stored at 2-8C. DO NOT FREEZE KIT COMPONNETS.  The microtiter plate should be kept in a sealed bag to minimize exposure to damp air. Use up the reagents as soon as possible after the kit is unpacked.
