FirstChoice™ Blocking Buffer is ideal as a first choice for optimization of new assays and systems, or when determining the optimal blocking buffer for elimination of non specific binding sites in ELISA, blotting, immunohistochemistry and other applications. Buffers are conveniently supplied in widely used TBS (Tris-buffered saline at pH 7,5) and PBS (phosphate-buffered saline at pH 7,5) buffers as well as in separate formulations containing Tween® 20 for improving blocking efficiencies.

Supplier: Rockland Immunochemicals

A blocking buffer specifically designed for western blotting using fluorochrome conjugated antibodies. Blocking buffer was prepared using ultra pure reagents dissolved in pharmaceutical grade water (WFI) and consists of a proprietary protein formulation in tris buffered saline at pH 7,6 with thimerisol added as an antimicrobial agent.

Blocking buffer is an enhanced blocking agent available in multiple formats. Superior™ Blocking Buffer contains a proprietary antigenically non-determinant protein for blocking Western blot membranes, blocking and storage of ELISA plates, and blocking prior to immunohistochemistry staining.

Supplier: G-Biosciences

Protein-Free™ Blocking buffer is a formulation of non-protein agents that eliminate non-specific binding sites in ELISA, blotting, immunohistochemistry and other applications. The absence of protein from the Protein-Free™ Blocking buffer eliminates problems associated with traditional protein based blockers, such as cross-reactivity and interference from glycosylated proteins.

NAP-BLOCKER™ is an animal-free protein blocking agent recommended for improved assay sensitivity, minimal non specific binding and a high signal-to-background ratio. It is suitable for Western blots, dot blots and assay development.

Supplier: Biotium

The TrueBlack® WB blocking buffer kit is a ready-to-use buffer system that provides optimal specificity, sensitivity, and background signal suppression for fluorescence-based western blotting (WB).

Supplier: Biotium

Fish gelatin is commonly used in blocking solutions to minimise background noise in immunodetection procedures such as Western Blotting and immunostaining. Fish gelatin can be used to block non-specific binding sites on positively charged nylon or PVDF membranes or for blocking and dilution of antibodies during immunostaining procedures. Unlike BSA or milk, fish gelatin does not contain IgG or serum proteins that could cross-react with mammalian antibodies.
