ExtrAvidin® Staining Kits

ExtrAvidin® staining kits are comprised of universal reagents for use with primary antibodies in immunohistology, ELISA, and immunoblotting. ExtrAvidin® is a unique form of avidin, available only from Sigma, that combines the high specificity and affinity of avidin for biotin with low non-specific binding at physiological pH. ExtrAvidin® alkaline phosphatase and peroxidase enzymes thus exhibit high sensitivity with low background.
