Virusys Corporation - About Antigens

Antigen should be supplied in buffered (Tris, MOPS, Hepes) saline solution.

Insoluble antigen (inclusion bodies) is as good as a soluble one.

Desired antigen concentration is 1 mg/ml, however lower concentrations are also acceptable.

You can also send us just a band cut out from SDS-PAGE gel, which contains protein of interest. Destain gel in water, since acetic acid will contribute to further denaturation of the protein.

Avoid:

Additives toxic to animals, e.g. protease inhibitors such as PMSF, sodium azide etc.

Acceptable:

Low amounts of SDS, imidazole, urea, guanidine, non-ionic detergents, EDTA or EGTA and polyacrylamide. Final amounts depend very much on sample volume/antigen concentration. Please, inquire.
