Methods Casein was hydrolyzed by trysin and chyomtrysin together. The enzymatic hydrolysis was filtrated by ultrafiltrate membrane, and analyzed by SDS-PAGE.
The ultrafilter should be sized to provide 3.0 gallons per minute of ultrafiltrate for each 100 ft. 2 /minute of coatable surface area even when flux rate is at low level.
