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. It is highly immunogenic, and probably accounts for most cases of egg allergy.
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.
Other Notes
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.
