Cofactors
Mode of action:
Each cofactor binds with a specific serine protease
When the serine protease is bound to a cofactor
it is more stable and more reactive
Factors that are cofactors:
Tissue factor (Factor III)
Factor VIIIa
Factor Va
HMWK
Protease it binds with:
Factor VIIa
Factor IXa
Factor Xa
Factor XIIa & Kallikrein
