Separation of protein C from Cohn Fraction IV-1 by mini-antibody.

Human protein C (PC) is a natural anticoagulant, antithrombotic, anti-inflammatory, and anti-apoptotic in the bloodstream. PC deficiency can lead to abnormal blood clot formation inside blood vessels, possibly causing heart attack, stroke, skin necrosis, or even death. PC can be, therefore, a valuable therapeutic with little side effect, unlike the currently used anti-coagulants.
