General description
Chicken egg albumin, or ovalbumin, is the major protein constituent of egg whites. Chicken egg albumin is a phosphorylated glycoprotein. From the amino acid sequence, the peptide portion of ovalbumin consists of 385 residues and has a molecular weight of 42.7 kDa.[1]
Application
A phosphorylated glycoprotein which is useful as a marker (~45 kDa) for protein electrophoresis. Has been used to produce an animal model of asthma.
Ovalbumin is useful as a marker (∼45 kDa) for protein electrophoresis. Ovalbumin has been used to produce an animal model of asthma. Ovalbumin was used as a medium for cell incubation in EliCell assay for the detection of released cytokines from eosinophils.[2]
Studies to test the effects of localization on DNA immunizations use ovalbumin in antibody assays.[3]
Ovalbumin has been used as an induction agent in model studies of atopic dermatitis.

Ovalbumin has been used as an induction agent in model studies of atopic dermatitis.
Biochem/physiol Actions
Differential scanning calorimetry indicates that chicken egg albumin denatures at 84 °C.[4] Ovalbumin can be used as a carrier protein to conjugate to synthetic peptides for use as an immunogen.
