Hep B cAg Antibody (13A9) is a mouse monoclonal IgG2b antibody that detects Hep B cAg protein of Hepatitis B by western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). Hep B cAg plays a crucial role in the life cycle of the Hepatitis B virus, as Hep B cAg encapsulates the viral genome and forms the core of the virus, which is essential for assembly and stability. Understanding the structure of Hep B cAg is vital because Hep B cAg not only aids in the diagnosis of Hepatitis B infection but also provides insights into potential therapeutic targets. The presence of Hep B cAg in the serum indicates active viral replication, making Hep B cAg a key marker for monitoring disease progression and treatment efficacy. Hep B cAg is primarily expressed in liver cells, where the virus replicates, highlighting the importance of liver health in the context of Hepatitis B infection. Anti-Hep B cAg antibody (13A9) enables researchers to effectively study viral dynamics and interactions within the host, contributing to the development of better diagnostic and therapeutic strategies against Hepatitis B.
