Human HbsAg (hepatitis B virus Surface Antigen) ELISA Kit (HUFI08043)

This qualitative immunoassay from Assay Genie screens human blood-derived specimens for the hepatitis B surface antigen, a key serological marker of active or chronic HBV infection. The enzymatic readout is performed on a microplate and is validated for diagnostic screening, blood-bank donor testing, and epidemiological surveillance workflows. The kit provides pre-coated plate wells, ready-to-use positive and negative controls, and conjugate reagents sufficient for up to 96 determinations, with a recommended sample volume of 50 uL per well and a total incubation time of approximately 2 hours at 37°C. Unopened components should be refrigerated, and the kit retains activity for up to 6 months when stored cold. Sensitivity is reported at approximately 0.5 IU/mL, supporting early detection of low-level surface antigenemia in clinical specimens.
