Hepatitis B Surface Antigen (HBsAg) - Subtypes AY & AD

Our Hepatitis B Surface Antigen (HBsAg) products-Subtype AY (Cat. #: A1280-AY), Subtype AD (Cat. #: A1280-AD), and AY Concentrate (Cat. #: A1290)-are derived from single human donors and confirmed HBsAg-positive. These reagents are ideal for assay development, diagnostic kit manufacturing, and hepatitis B virus (HBV) research.

Each material is filtered (0.2 µm), phosphate-buffered, and stabilized with defined excipients. All lots are tested non-reactive for HIV 1/2, HCV, and Syphilis using FDA-approved methods. Products are intended for research use or manufacturing of non-injectable products only.

Key Features:

• Available subtypes: AY (A1280-AY), AD (A1280-AD), and AY Concentrate (A1290)
• Liquid form, single-donor source, 0.2 µm filtered
• Subtypes AY/AD stored at 2-8°C; concentrate stored at -20°C
• Buffered in phosphate solution with NaCl, sucrose, and sodium azide
• Non-reactive for HIV, HCV, and Syphilis

Applications:

• Development of hepatitis B serological assays (e.g., ELISA, CLIA)
• Assay calibration, controls, and validation studies
