additional information
Rattus norvegicus
cancer procoagulant is a cysteine protease acting as an activator of coagulation factor X, the protein activates factor X in the absence of tissue factor and factor VII
?
additional information
Rattus norvegicus
rat and human cancer procoagulant activity bind similarly to antiCP antibodies

Organism
Rattus norvegicus
Lobund-Wistar rat with transplanted PA-3 prostate tumors
Purification (Commentary)
harvested PA3 tumors are extracted in 0.02 M Tris (pH 7.8), after centrifugation extracts are purified by ion-exchange chromatography, fractions containing CP activity are desalted and concentrated by ultrafiltration on YM10 membrane and redissolved in 2-3 ml of 0.02 M Tris
