The Expedeon Lightning-Link® Streptavidin antibody labeling kit enables the direct conjugation of antibodies, proteins and peptides, or any other biomolecule with an available amine group, to streptavidin with only 30 seconds hands-on time and with 100% recovery of materials. The technology is fully scalable from 10ug to 1g or more and stringently QC tested for consistent high quality and excellent batch to batch reproducibility.
Streptavidin is a 53kDa protein purified from Streptomyces avidinii, which has widespread applications due to its very high affinity to the vitamin biotin. It is a tetrameric molecule, composed of four 13kDa monomers, each of which can bind a molecule of biotin.
