HBcAg (core antigen) is a hepatitis B viral protein. [1][2] It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).

Oct 29, 2021 · The hepatitis B core antigen (HBcAg) is part of the nucleocapsid within HBV; it is not routinely measured in clinical practice; however, the body produces a corresponding antibody to this antigen called hepatitis B core antibody (anti-HBc), which is clinically relevant.

Hepatitis B core-related antigen (HBcrAg) is a novel biomarker that has an important role in chronic hepatitis B (CHB), because it correlates with serum HBV DNA and intrahepatic cccDNA.

Hepatitis core antigen (HBcAg) is a protein translated from HBV core ORF and component of HBV nucleocapsid. HBcAg is present intracellularlly and not routinely detectable in the serum of infected individuals. Antibodies to core protein (anti-HBc) are the host's immune response that can be divided into IgM and IgG.

HBcAg is an attractive antiviral target because dimer and capsid participate in several steps of the virus life cycle (153, 154). Misdirection of in vitro assembly by altering temperature and ionic strength can lead to formation of kinetically trapped intermediates or …

Hepatitis B Surface Antigen (HBsAg) – The "surface antigen" is a protein found on the surface of the hepatitis B virus that is present in the blood of someone who is infected. If this test is positive or "reactive," then the hepatitis B virus is present.

HBcAg is a core antigen that forms the inner core of the virus particle. It is composed of a single polypeptide chain and is highly immunogenic. In contrast, HBsAg is a surface antigen that is found on the outer surface of the virus envelope.

HBcAg and hepatitis B e antigen (HBeAg) are translated from a common gene but display different antigenic properties. HBcAg, the nucleocapsid protein, is found in liver tissue in patients with acute or chronic HBV infection.

Hepatitis B core-related antigen (HBcrAg) is an unprecedented, new HBV marker that plays a pivotal role in reflecting cccDNA in CHB because it is associated with not only serum HBV DNA but also intrahepatic cccDNA.

hepatitis B core antigen (HBcAg) a core protein antigen of the hepatitis B virus present inside complete virions (Dane particles) and in the nuclei of infected hepatic cells, indicating the presence of reproducing hepatitis B virus.
