NAME AND INTENDED USE

 

Bioneovan HBcAb ELISA Kit is an in vitro enzyme linked immunoassay supplied for the detection of HBcAb in human serum or plasma. It is intended for use in clinical laboratories for diagnosis and management of patients related to infection with hepatitis B virus

 

 

Hepatitis B is an infectious illness caused by hepatitis B virus (HBV) which is an envelope, double-stranded DNA virus belonging to the Hepadnaviridae family and is recognized as the major cause of blood transmitted hepatitis together with hepatitis C virus (HCV). HBV is excreted in body fluids such as semen, saliva, blood and urine in persons with acute or chronic infection. The hepatitis B virus is known as a blood-borne virus because it is transmitted from one person to another via blood or fluids contaminated with blood. Transmission of hepatitis B virus results from exposure to infectious blood or body fluids.When HBV invades the body it causes liver damage through induction of auto-immunity. Three immunity has been found, surface antigen (HBsAg)/HBsAb, core antigen (HBcAg)/HBcAb and antigen (HBeAg)/HBeAb. As it is difficult to detect the core antigen in the serum, the other five are been done to diagnosing HBV. Hepatitis B “core” antigen (HBcAg) is a major component of the viral structure. Antibodies to HBcAg (anti-HBc total antibody, and IgM) appear shortly after the appearance of HBsAg and persist for life both in persons who have recovered from a hepatitis B infection and in those who develop HBsAg-carrier status but in rare cases, a HBV infection can also run its course without the appearance of immunologically detectable anti-HBc (usually in immunosuppressed patients). Anti-HBc is a marker of acute, chronic or resolved HBV infection and screening for anti-HBc provides with information on the prevalence of the disease in different groups. In the absence of other hepatitis B markers (HBsAg-negative persons), anti-HBc may be the only indication of an existing hepatitis B viral infection.

PRINCIPLES OF THE ASSAY

 

This HBcAb ELISA Kit is based on solid phase, one step incubation competitive principle method. Anti-HBc if present in the sample, compete with monoclonal anti-HBc conjugated to horseradish peroxidase (HRP-Conjugate) for a fixed amount of purified HBcAg pre-coated in the wells. When no anti-HBc presents in the sample, the HRP-conjugated anti-HBc will be bound with the antigens inside the wells and any unbound HRP-Conjugate is removed during washing.

The enzyme substrate, tetramethylbenzidine (TMB), is added upon incubation the substrate will be hydrolyzed by the bound enzyme and a blue or blue-green color develops in wells containing specific antibodies to HBcAg. The enzyme reaction is stopped by the addition of sulphuric acid. The intensity of color developed is read spectrophotometrically at 450nm (450 nm/630 nm) and is proportional to the amount of antibodies present in the specimen. No or low color developing suggests for presence of antibodies to HBcAg in the sample.
