Descripción

Descripción general

Ovomucoid or trypsin inhibitor is an abundant protein in most avian egg whites. The hen′s egg protein is composed of about 186 amino acid residues, and is highly glycosylated. Three tandem domains are each homologous with pancreatic trypsin inhibitor. It is highly immunogenic, and probably accounts for most cases of egg allergy.

Aplicación

Trypsin inhibitor from chicken egg white has been used:

• to terminate proteolysis reaction
• in OVO-1 solution to triturate the cell suspension for the dissociation of retina
• in phosphate buffered saline for dissociation of cortices

Acciones bioquímicas o fisiológicas

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.

Definición de unidad

One trypsin unit will produce a ΔA₂₅₃ of 0.001 per min with BAEE as substrate at pH 7.6 at 25 °C; reaction volume 3.2 mL, 1 cm light path.
