MAGICLINK™ Site Specific Kits provide optimized reagents for labeling antibodies. The most important features of the kits are ultra-fast reaction speed, high conjugation efficiency, and the most stable linkage between antibody and streptavidin on the market to date. Labeling reactions chemiselectively target disulfide bonds for maximum labeling efficiency. The kits provide optimized reagents for conjugating LINK modified streptavidin to antibodies or other proteins with disulfide bonds. Each 100 μg kit reaction is sufficient for labeling 50-200 μg of antibody in 100 μL reaction volumes, and 500 μg kit for 500 - 1000 μg antibody. The MAGIC Site-Specific linker, provided as a controlled excess reagent, reacts with the antibody under mild alkaline pH conditions. The MAGIC-antibody then reacts instantly with LINK-Streptavidin to get the Streptavidin-Antibody conjugate.
The Site-Specific Streptavidin Labeling Kit is used to conjugate streptavidin with primary antibodies, recombinant antibodies or proteins with free thiols or disulfide bonds. The streptavidin conjugates have wide applications below.
