Stability Moisture Sensitive
Applications Succinimidyl-6-(biotinamido) Hexanoate is a biotinylation reagent incorporating an aminocaproyl “spacer”. This can reduce the steric hindrance in binding avidin to some biotinylated compounds when used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin Capture System. This system avoids the direct interaction of a captured antibody with solid surfaces, such as plastics, which may reduce antigenicity. It has also been used to enhance the detection of DNA on nitrocellulose. Has also been used as a cell surface labelling reagent
