Relevance Storage protein of egg white. Lack protease inhibitory activity.
  • (Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Description Ovalbumin is a native protein with full length. This protein is purified from chicken egg white. Its purity was determined by SDS-PAGE and reached up to 95%. It is presented the mass molecule around 45 kDa visualized on the gel. It has been validated in ELISA, WB and SDS-PAGE applications.
Ovalbumin (OVA) is the main protein found in egg white proteins (EWP), which has good functionality, particularly foaming and gelling properties. OVA is a globular protein containing 385 amino acid residues, 1 disulphide bond, and 4 free sulphydryl groups. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. Although it is presumed to be a storage protein, the function of ovalbumin is still unknown.
