Create a label-ready site-specific azido-modified antibody without lengthy and inefficient genetic modification using the SiteClick Antibody Azido Modification Kit. SiteClick labeling uses enzymes to specifically attach an azido moiety to the heavy chains of an IgG antibody, ensuring that the antigen binding domains remain unaltered 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. Once azido–modified, a variety of labeled SiteClick sDIBO alkynes are available for attachment to the antibody via Click chemistry at your choice of scale. This provides the flexibility to choose different labels for your antibody depending on your assay.

Features of the SiteClick Antibody Azido Modification Kit:
• Contains everything required to azido-modify any species or isotype of IgG antibody
• Easy-to-follow step-by-step protocol
• Highly efficient, site-specific, reproducible labeling chemistry results in high quality antibody conjugate
