General description

Ovomucoid or trypsin inhibitor is an abundant protein in most avian egg whites. Three tandem domains are each homologous with pancreatic trypsin inhibitor.[1] It is highly immunogenic, and probably accounts for most cases of egg allergy.[2]

Unit Definition

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.

Analysis Note

One mg will inhibit 0.9-1.3 mg of trypsin with activity of approx. 10,000 BAEE units per mg protein or 0.4-1.0 mg of α-chymotrypsin with activity of approx. 40 BTEE units per mg protein.
