Catalog number:  S20033

Back to top


Unlike the conventional amine-thiol crosslinker labeling method, the SiteClick Biotin Antibody Labeling Kit specifically attaches the label to the heavy chains of an IgG antibody, ensuring that the antigen-binding domains remain available for binding to the antigen target. This site selectivity is achieved by targeting the carbohydrate domains present on essentially all IgG antibodies regardless of isotype and host species. In addition, no harsh reduction steps are required, and the labeling is consistent and reproducible.

Features of the SiteClickBiotin Antibody Labeling Kit:
• Contains everything required to label 100–250 µg of IgG antibody
• Easy-to-follow step-by-step protocol
• Highly efficient, site-specific, reproducible labeling chemistry results in high quality antibody conjugate
