Biotin is used for mmunological purification in avidin/streptavidin-biotin binding mechanisms. Biotin, also known as vitamin H or B7, is a water-soluble B-complex vitamin which is composed of an ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring. Applications: Suitable for use in Western Blot, ELISA and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:20,000- 1:200,000 Western Blot: 1:10,000- 1:40,000 Immunohistochemistry: 1:1000- 1:5000 Optimal dilutions to be determined by the researcher.
