Biotinylated secondary antibodies

We offer biotinylated secondaries to use with avidin or streptavidin based methods such as ABC or LSAB. Avidin or streptavidin form strong complexes with biotin providing high signal amplification due to the large binding capacity of biotin (up to four molecules of avidin or streptavidin).
