Vector Laboratories, Inc. products

Streptavidin/Biotin Blocking Kit blocks all endogenous biotin, biotin receptors, and streptavidin binding sites present in tissues. This kit is designed for use with streptavidin detection systems such as the VECTASTAIN^® Universal Quick kits if streptavidin or biotinylated reagents bind non-specifically to tissues or proteins. This blocking kit consists of 18 ml Streptavidin and 18 ml of biotin in convenient dropper bottles.

Avidin/Biotin Blocking Kit blocks all endogenous biotin, biotin receptors, and avidin binding sites present in tissues.  This kit is designed for use with avidin detection systems such as the VECTASTAIN^® ABC Kits if avidin or biotinylated reagents bind non-specifically to tissues or proteins. This blocking kit consists of 18 ml of Avidin D and 18 ml of biotin in convenient dropper bottles.

Polymer-based reagents are a more recent introduction into IHC detection methodology than traditional avidin and biotin conjugates, such as ABC kit formats. Polymers offer distinct advantages over these traditional methods particularly for applications such as multiple antigen labeling (multiplexing) on the same tissue section, or in instances where detectable levels of endogenous biotin may be problematic.

WestVision™ Peroxidase Polymer antibody conjugates are based on a proprietary method of polymerizing enzymes and attaching these enzyme polymers to antibodies. The result allows a higher density of enzymes to access a target with minimal interference, providing excellent signal-to-noise-ratio in western blot detection.
