Background Punisher is a universal blocking reagent for reducing nonspecific background staining often found in IHC and ELISA techniques. This proprietary combination of proteins can be used on both human and animal tissue.

Peroxabolish is a non-hydrogen peroxide blocking reagent that extremely gentle. It is highly effective in quenching endogenous peroxidase and can be used on FFPE tissues, cell culture, blood smears, cell preparations and frozen sections.

Blocking reagent for use with primary antibodies from mouse host and mouse tissue.

Streptavidin/Biotin Blocking Kit (SP-2002) blocks all endogenous biotin, biotin receptors, and streptavidin binding sites present in tissues. This kit is designed for use with streptavidin detection systems if streptavidin or biotinylated reagents bind non-specifically to tissues or proteins. This blocking kit consists of 18 ml of streptavidin and 18 ml of biotin in convenient dropper bottles. The streptavidin solution is applied first (mixed with normal blocking serum), followed by the biotin solution.

Immunofluorescence Blocking Buffer 50 ml

Peptide Blocker delivers complete eradication of background staining of animal, human tissues & cells stained by IHC, IF, in situ ( frozen, paraffin) & free floating sections; Short incubation step. A must for Mouse-on-Mouse staining

XR Factor is a potent blocker for eliminating endogenous rat IgG in rat tissues. XR Factor is formulated for use with anti-mouse, rabbit or goat PromARK micro-polymer detection systems.

Background Punisher is a universal blocking reagent for reducing nonspecific background staining often found in IHC and ELISA techniques. This proprietary combination of proteins can be used on both human and animal tissue.

Background Sniper is a universal casein blocker used for reducing nonspecific background staining often found with IHC, ELISA, immunoelectron microscopy and immunogold techniques. Casein has proven to be a superior blocking reagent.

Normal Serum Block Apps: IHC; Size: 50 mL

The use of Cold Water Fish Skin Gelatin to prevent background reactions has been recommended by e.g. Behnke et al. (J. Cell Biol. 41, [1986], 386). The product is supplied as a liquid concentrate (40%).

Normal Serum Block Apps: IHC; Size: 15 mL

V-Blocker is a universal blocking reagent used for reducing nonspecific background staining often observed on an automated staining system. It is formulated for superior pH stability and is sodium azide and thimerosal free.

Block Ace is designed as a high-performance blocking reagent for use in immunological assays such as ELISA and Western blotting. It may also be used for dilution of antibodies and for washing procedures in the above assays.

PAP GnomePen liquid blocker is a proprietary formulation that is applied around the tissue sections on a microscope slide prior to immunohistochemistry. It dries in less than one minute! Also, it has one of the thinnest tips available for a PAP pen and easily allows for adjacent circles on a slide to be drawn.

Background Eraser is a 10% goat serum with surfactant blocker that has been optimized to work with Biocare's 4plus avidin-biotin detection systems. Ideal for when secondary antibodies have been derived from goat.

Peroxabolish is a non-hydrogen peroxide blocking reagent that extremely gentle. It is highly effective in quenching endogenous peroxidase and can be used on FFPE tissues, cell culture, blood smears, cell preparations and frozen sections.

XM Factor is a potent blocker for blocking endogenous mouse IgG in mouse tissues. XM Factor is formulated for use with anti-rat, rabbit or goat PromARK micro-polymer detection systems.
