Negative Isotype Controls
- Hepatitis B virus is a major causative agent of acute and chronic liver disease in humans. Hepatitis B surface antigen (HBsAg) is a protein component of the viral envelope, which is expressed predominantly in the cytoplasm of infected hepatocytes.
Hepatitis B surface antigen subtype ay purified from human plasma - liquid
Hepatitis B surface antigen subtype ay was purified by three ultracentrifugation steps from human plasma. The preparation was inactivated by heat treatment for 10 hours at 60°C.
This product has been rendered inactive by standard procedures. However this material should still be handled as infectious and should be disposed of appropriately.
1) Silver stained SDS-PAGE under reducing conditions reveal two major bands corresponding to p24 and gp27. Bands corresponding to pre-S proteins, dimers and 69kDa protein also detected.
2) 20nm spherical particles were detected by electron microscopy, as well as rod particles in some lots. Complete virions (Dane particles, 42nm) were not observed (done initially when the protocol was established).
