Anti-Protein S Antibody

Polyclonal antibody raised in rabbit against human Protein S, a vitamin K-dependent plasma glycoprotein that serves as a cofactor for activated protein C in the anticoagulation cascade. This unconjugated primary antibody from Antibodies.com is validated for Western blot and immunofluorescence applications and specifically recognizes the human target, enabling detection of the single-chain ~70 kDa protein in cell and tissue-derived samples. Each vial is supplied as 100 µL of antiserum, useful for multiple immunoblotting or imaging experiments when paired with appropriate secondary detection reagents. The reagent is produced by immunization and purified by standard methods to deliver batch-to-batch consistency for laboratory research into coagulation biology, thrombotic disease mechanisms, and PROS1 gene expression studies. Store at -20°C in working aliquots to preserve activity and avoid repeated freeze-thaw cycles.
