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: VWR Chemicals

La solution RapidBlock™ réduit le temps de blocage à 5 minutes pour les procédures de transfert Western et de « dot blot » sur membranes en PVDF et nitrocellulose. Cette formule sans protéines minimise la réactivité croisée et les liaisons aux anticorps non spécifiques, en produisant des transferts avec un bruit de fond faible et un meilleur rapport signal/bruit.

Chaque paquet de tampon de blocage en poudre permet d'obtenir un litre de solution 1X.

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.

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.

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: 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.

Supplier: G-Biosciences

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: Biotium
