Effects of washing and oiling with liquid paraffin on horizontal polyacrylamide gradient gel electrophoretic patterns of albumen obtained from the chicken shell eggs stored for 11 weeks at 25°C were studied. In unwashed and unoiled shell eggs stored from 3 to 11 weeks, the distinct dense ovotransferrin bands were disappeared, but a diffuse anodally migrating ovotransferrin band was detected. Ovalbumin A1, ovoglobulin G3, ovoglobulin G4 and ovoglobulin G2 were detected as more diffuse and slightly more acidic bands than those of fresh albumen.Electrophoretic patterns of washed and unoiled eggs stored for 1 week were comparable with those of albumen obtained from unwashed eggs stred for 3 weeks. Oiling resulted in apparently a better resolution of electrophoretic patterns of albumen proteins of shell eggs as compared with those of the unoiled shell eggs through storage period from 0 to 11 weeks.
