UltraBlock-Casein™ Phosphate Buffered Saline 5X (B401-GRP)

UltraBlock-Casein™ Phosphate Buffer Saline Blocking Buffer/Diluent is a proprietary formulation of many phosphoserine groups that function to bind Ca2+. This reagent may be used as a blocking buffer for direct and sandwich ELISA’s or as a diluent for all immunoassays. The buffer will minimize non-specific binding of secondary reagents to one another and with the plate bound protein. The small molecular weight of casein also provides blocking of uncoated regions of the micro ELISA wells that are inaccessible to traditional mammalian blocking reagents, such as BSA
