HRP

Signal amplification methods are widely used in immunohistochemistry (IHC) for detection of rare epitopes and low abundance antigens. While many of these techniques such as the avidin-biotin complex (ABC) method improve staining, they frequently require additional steps and result in higher background staining.  Blocking endogenous biotin, a requirement of using ABC reagents, may not sufficiently remove residual activity in frozen tissue sections and tissues high in biotin including the liver and kidney.

One satisfied customer wrote, "Fast, efficient, stable direct HRP conjugation - best reagent we have found..." Another reviewer wrote, "This conjugation kit worked beautifully [and] the procedure is so simple. Although we had some [initial] concerns, it worked very well."
