Biotin Labeling Reagents

Biotin labeling reagents are available from a number of suppliers to facilitate the conjugation of proteins with biotin. Biotin is a frequently used label due to its small size and strong affinity to the proteins avidin and streptavidin. Protein biotinylation, or the covalent attachment of biotin, can be accomplished through biotin reagents with reactive groups, such as alkynes, azides, maleimides, hydrazides, and NHS esters. The labeling process generally proceeds via a simple reaction and purification process. Biotinylated proteins can then be detected or purified using immobilized or conjugated avidin or streptavidin.
