Ovalbumin (abbreviated OVA) is the main protein found in egg white, making up 60-65% of the total protein. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily. The function of ovalbumin is unknown, although it is presumed to be a storage protein or carrier protein.
Applications
Suitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested.
Recommended Dilution
ELISA: 1:1000-1:5000 Western Blot: 1:500-1:2500 Optimal dilutions to be determined by the researcher.
