一般描述
Hepatitis C virus core antigen (HCV-cAg) is a well-preserved antigenic protein of the internal capsid.
Hepatitis C virus glycoprotein 1 (HCVgp1), also referred to as polyprotein, is crucial for the induction of double-membrane vesicles, sites of HCV RNA amplification. The amino terminal of polyprotein contains the structural proteins core, envelope protein 1 (E1) and E2. The proteolytic cleavage of polyprotein results in the formation of 10 mature viral proteins which are needed for viral replication and assembly.
amino acids 2-192 of HCV polyprotein
特异性
Reacts strongly with human HCV positive serum.
应用
Hepatitis core antigen (HCA) has been used as an analyte in enzyme-linked immunosorbent assay (ELISA) to study the mechanism of bovine serum albumin (BSA) blocking in common ELISA protocols.
生化/生理作用
Hepatitis C virus core antigen (HCV-cAg) may be a less expensive way to diagnose active hepatitis C virus (HCV) infection in the hemodialysis (HD) population.
Positive control for HCV antibodies.
其他说明
HCV core antigen [2-192]-Galactosidase-tagged at the N-terminus.
