Background: Cleaves the vWF multimers in plasma into smaller forms thereby controlling vWF-mediated platelet thrombus formation.Zinc and calcium ions cooperatively modulate enzyme activity. The cleavage of the pro-domain is not required for protease activity. Dependence on calcium for proteolytic activity is mediated by the high affinity site.
Sequence: Thr 1151-Thr 1427
Purity: > 95 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual.
