Blocking Buffers & Diluents

Filter
LLBB - Blocker Buffer-BSA

BioFX® Blocking Buffer-BSA is designed for use in most direct and sandwich ELISA assays requiring low to average blocking strength. It is suitable for most monoclonal and polyclonal antibody capture ELISA formats, and peptide and protein antigen-down ELISA formats. Proprietary proteins provide a long-term stabilizing environment for dried coated antibodies or antigens and minimize non-specific binding.

MLKB - BBS/MILK BLOCK 10X

BioFX® Borate Buffered Saline (BBS) Milk Blocking Solution-10X Concentrate contains Non-Fat Dry Milk (NFDM) in a BBS solution that is supplied as a solution ready for dilution to specific application requirements. This product serves as a blocking reagent when diluted in reagent quality water. As a blocking reagent, the solution binds to the secondary protein binding sites following the binding of the primary antigen or antibody to the solid phase surface.

NMBB - Blocking Buffer-Fish

BioFX® Blocking Buffer-Fish is designed for use in most direct and sandwich ELISA assays requiring high blocking strength. The formulation blocks non-specific binding sites of the coated protein and the unoccupied areas of the plate which are not accessible to the larger, traditional blocking reagents.

PBSC - Phosphate Buffered Saline/Casein Block & Diluent-5X

BioFX® Phosphate Buffered Saline/Casein Block and Diluent-5X Concentrate minimizes non-specific interactions of the secondary reagents with each other and the primary solid phase binding sites. The high blocking efficiency of casein is due to its content of small molecular weight proteins. The solution is ready for dilution to specific application requirements.

STSB - Blocking Buffer-Synthetic

BioFX® Blocking Buffer – Synthetic is a formulation designed for use in most direct and sandwich ELISA assays requiring high blocking strength without the cross-reactivity risk associated with protein blocks.

TBSC - TBS/CASEIN 10X

BioFX® Tris Buffered Saline (TBS)/Casein Block and Diluent – 10X Concentrate minimizes non-specific interactions of the secondary reagents with each other and the primary solid phase binding sites. The high blocking efficiency of casein is due to its content of small molecular weight proteins. The solution is ready for dilution to specific application requirements.
