HEMOSTASIS COAGULATION RESEARCH REAGENTS VENOM PROTEASES AGKISTRODON CONTORTRIX VENOM SNAKE
Protac
Product derived from Agkistrodon contortrix venom in lyophilized form.
Protac is used for the determination of protein C and protein S levels in plasma.
Molecular Weight (Da) : 36 000 à 42 000
Protac, a single chain glycoprotein, is a fast-acting protein C activator isolated from the venom of the copperhead snake Agkistrodon contortrix and closely related snake species. This serine proteinase rapidly converts protein C of man and other vertebrates into activated protein C which may be determined either by measuring its prolonging effect on the activated partial thromboplastin time (APTT) or by measuring its enzyme activity by means of a specific chromogenic substrate.
Advantages
The venom proteases offered are highly purified, homogenous preparations with the indicated activities.
Informations
Snake venom proteases are useful tools for studying coagulation reactions. Venoms contain more than 20 different compounds, mostly proteins and polypeptides. Some of the proteins in snake venom have very specific effects on various biological functions including blood coagulation, blood pressure regulation, transmission of the nervous or muscular impulse and have been developed for use as diagnostic tools. Plasma coagulation Factors are usually inactive and require proteolytic activation as a first step towards a chronometric or colorimetric assay. It is often advantageous to use specific enzymes from snake venoms to activate coagulation Factors rather than physiological activators. In contrast to other activators, many snake venom enzymes are not dependent from cofactors, phospholipid or calcium ions.
