Using AB serum eliminates blood-type-specific lysis, agglutination and assay interference that can occur with Type A, B or O serum. This broad compatibility is critical in ELISA matrix development, lateral flow assay calibration and IVD manufacturing where consistent matrix properties across lots are essential.<\/p>\n        <\/details>\n\n        <details class=\"sb-hs-ab-faq-item\">\n          <summary>What is the difference between Human Serum Type AB and Human Serum Type AB Male?<\/summary>\n          <p>Both are AB-type, standard clotted serum. Human Serum Type AB is sourced from mixed-gender donors, while Human Serum Type AB Male comes exclusively from male donors. Male-donor serum eliminates female-specific hormonal variability and carries no TRALI (Transfusion-Related Acute Lung Injury) risk from HLA antibodies. Type AB Male is preferred when tighter lot-to-lot consistency is required \u2014 for example in long-term assay development, clinical diagnostic manufacturing or studies sensitive to hormonal background variation.<\/p>\n        <\/details>\n\n        <details class=\"sb-hs-ab-faq-item\">\n          <summary>Is heat inactivated (HI) or gamma irradiated (GI) Human Serum Type AB available?<\/summary>\n          <p>Yes. Both heat inactivated (56 \u00b0C, 30 min) and gamma irradiated versions are available on request. Heat inactivation destroys complement activity \u2014 important for applications where complement interference would affect readouts. Gamma irradiation provides pathogen inactivation for biosafety-critical applications. Low-endotoxin specifications are also available.
