Features: Avidin and streptavidin reagents are powerful tools to detect or purify biotinylated proteins, nucleic acids, and other macromolecules. Horseradish Peroxidase Avidin D (HRP Avidin D) is produced by our own coupling procedure which preserves the high specific activity of the peroxidase. Using biotinylated primary or secondary intermediates and peroxidase-labeled Avidin D, antigens can be localized in histological sections, cytospin preparations, or smears. Horseradish Peroxidase Avidin D is offered as a concentrate (5 mg/ml) or in a ready-to-use (R.T.U.) stabilized solution (100ml,1µg/ml) in a bottle fitted with a drop dispenser top. For horseradish peroxidase labeled Avidin D (Av-HRP) that is optimized for use in solid-phase assays such as ELISAs and blotting applications, see the following product: Avidin D, Horseradish Peroxidase (Av-HRP), Concentrate, for ELISAs and Blots
