Anti-PROS1 Antibody

Polyclonal antibody raised in rabbit against the human vitamin K-dependent plasma glycoprotein Protein S (encoded by PROS1), supplied unconjugated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as cryoprotectant. Provided as a 100 µl vial from Antibodies.com, the reagent is validated for Western blot and immunohistochemistry on human, mouse, and rat samples, supporting both lysate-based and formalin-fixed tissue-section workflows.

Protein S functions as a cofactor for activated protein C within the natural anticoagulant cascade, so the antibody enables investigation of coagulation factor regulation, thrombotic risk mechanisms, and vascular biology. Aliquoting on first use and refrigerated storage at 4 degrees C preserve activity across repeated freeze-thaw cycles for ongoing immunodetection programs in the research laboratory.
