Human Serum – Off the Clot Type AB (Male Donor), US or EU Origin

SeamlessBio Human Serum – Off the Clot Type AB (Male Donor) is collected from certified donor centers in the United States and the European Union under controlled conditions.
The serum is obtained from whole blood allowed to clot naturally without anticoagulants, preserving the physiological composition of proteins, hormones, and growth factors.

Each batch is sterile filtered (0.2 µm) and processed under GMP-aligned standards, available exclusively as heat-inactivated or gamma-irradiated product to ensure biosafety and reproducibility in sensitive research and diagnostic workflows.

Because Type AB serum lacks anti-A and anti-B antibodies, it is ideal for human cell culture, immunological assays, and diagnostic development where cross-reactivity must be minimized.

Key Features
