General description
卵类粘蛋白或胰蛋白酶抑制剂是大多数禽蛋白中富含的蛋白质。鸡蛋白约由186个氨基酸残基组成,且高度糖基化。三个串联的结构域均与胰蛋白酶抑制剂同源。其免疫原性很高,而且可能是大多数鸡蛋过敏的原因。Application
Trypsin inhibitor from chicken egg white has been used:
• to terminate proteolysis reaction[2]
• in OVO-1 solution to triturate the cell suspension for the dissociation of retina[4]
• in phosphate buffered saline for dissociation of cortices[3]
包装
1, 5 g in poly bottle
250, 500 mg in poly bottle
Biochem/physiol Actions
Ovomucoid possesses trypsin inhibitor activity. It has several conformational and linear epitopes that can be bound by immunoglobulin E (IgE). It is highly stable against heat and proteolysis.[1]
Unit Definition
