Our Frozen & Lyophilized Deficient Plasmas category offers essential, high-quality reference materials for the functional assay of coagulation factors, crucial for diagnosing congenital deficiencies and standardizing factor assays. We provide an extensive collection of plasmas, available in both frozen (-60°C) and lyophilized formats, from leading manufacturers including HYPHEN BioMed, Affinity Biologicals Inc., and 5-Diagnostics. This comprehensive range features plasmas specifically deficient in individual coagulation factors, such as Factor V, VII, VIII, IX, X, XI, XII, and XIII, as well as regulatory proteins like Protein C, Protein S, Antithrombin (AT), and fibrinolytic components like Plasminogen (PLG) and α2-Antiplasmin (α2-AP), ensuring precise calibration and reliable testing across the entire haemostasis pathway.
