Hepatitis B Serum
Hepatitis B Serum — serum from clinically confirmed hepatitis B donors, frozen within 24 hours. Ideal for HBsAg, anti-HBs, HBeAg and anti-HBc immunoassay development, HBV DNA quantification, genotyping, and functional cure biomarker research. HBeAg status, viral load, treatment status, and co-infection available for stratification. Samples contain infectious virus.
Hepatitis B Serum for Infectious Disease and Virology Research
Our Hepatitis B Serum is sourced from IRB-consented donors clinically diagnosed with hepatitis B. Each sample is processed and frozen within 24 hours of collection to preserve viral antigens, antibodies, and nucleic acid for serological and virological analysis. Serum is acellular, and is the standard matrix for HBV serology and viral load measurement.
HBV Virology and Why Serum
Hepatitis B is a chronic viral infection of the liver, caused by hepatitis B virus, a small partially double-stranded DNA virus with a strict hepatocyte tropism. Its biology is defined by persistence, not by autoimmunity:
- Persistence via cccDNA. HBV establishes a stable episomal covalently closed circular DNA reservoir in the hepatocyte nucleus, which current therapy suppresses but does not eliminate — the central obstacle to cure
- Serology is unusually informative. HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc in IgM and IgG classes together distinguish acute from chronic infection, resolved infection, and vaccine-induced immunity
- Chronic infection moves through recognised phases defined by HBeAg status, HBV DNA level, and degree of hepatic inflammation, so phase annotation matters more than diagnosis alone
- Liver damage is immune-mediated — HBV is not directly cytopathic; hepatocyte injury reflects cytotoxic T-cell responses, and chronic infection is characterised by T-cell exhaustion and a blunted antiviral response
- Genotypes A to J differ in geographic distribution, clinical course, and treatment response, and long-standing chronic infection carries risk of cirrhosis and hepatocellular carcinoma
- Why serum: serum supports quantitative HBsAg and antibody immunoassays, HBV DNA quantification and sequencing, and biomarker work toward functional cure, whose principal endpoint is sustained HBsAg loss
Donor Stratification Available
- HBeAg status: HBeAg-positive or HBeAg-negative chronic infection
- Viral load category and quantitative HBsAg level where clinically measured
- Treatment status: treatment-naive, on nucleos(t)ide analogue therapy, or previously treated
- Liver disease stage, including presence of cirrhosis where documented
- Co-infection status, including hepatitis C, hepatitis D, or HIV
- Genotype where clinically determined; age, sex assigned at birth, and race/ethnicity
- Matched healthy and vaccinated (anti-HBs positive) controls available
