Ovalbumin Native Protein Summary

Description
Ovalbumin is a glycoprotein that comprises 54% of the total proteins of egg white, and is important in several areas of research such as: protein structure , serpin structure and function, proteomics, and immunology.

Source: Native protein purified from Egg Whites

Preparation
Method
Native protein purified from Egg White
Source
Egg white
Protein/Peptide Type
Native Protein
Gene
OVAL
Purity
>80% by SDS-PAGE and Coomassie blue staining

Applications/Dilutions

Dilutions
  • SDS-Page
Application Notes
Ovalubin is very stable in the lyophilized state, we recommend making (1-10mg/ml) solutions as needed. Frozen stocks of ovalbumin in water at 5 mg/ml have been stable in QC for at least a month. Reconstituted stability is diluent, concentration, technique, and application specific.
Theoretical MW
45 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

Storage
Store at -4C in powder form. Store at -20C once reconstituted.
Preservative
No Preservative
Concentration
LYOPH
Purity
>80% by SDS-PAGE and Coomassie blue staining
Reconstitution Instructions
Reconstitute in sterile water at 1-10mg/ml. We do not recommend reconstituting entire 1g, instead you may weight out a smaller amount, reconstitute it, aliquot, and store at -20/-80C. The remainign powder should remain stored at 4C.

Notes

This product is produced by and distributed for Abnova, a company based in Taiwan.

Background

Chicken Ovalbumin is the major protein in the "white" of the egg (and a favorite antigen in immunological research). Egg white contains a variety of proteins including ovalbumin, conalbumin, ovomucoid and lysozyme. It belongs to the serpin family and the Ov serpin subfamily. Ovalbumin can cause an allergic reaction in humans. Ovalbumin has been implicated in the development of the egg shell. Immunohistochemistry revealed that ovalbumin is found only in the mammillary bodies of decalcified shell, and is not distributed throughout the shell matrix. These results indicate that ovalbumin is present during the initial phase of shell formation and becomes incorporated into the protein matrix of the mammillary bodies. However, it is not yet clear whether ovalbumin at this site plays a specific role in shell mineralisation.
