Protein Method Blocking Buffers
SCANTIBODIES LABORATORY INC HETEROPHILIC BLOCKING TUBE (3IX762) 50PK
The 3IX762 HBT (Heterophilic Blocking Tube) from Scantibodies Laboratory, Inc. contains a unique blocking reagent composed of specific binders which inactivate heterophilic antibodies. Once the specific binders have bound to the heterophilic antibodies, the antibodies are no longer able to cause immunoassay interference. The reagent is in the form of a lyophilized pellet at the bottom of the tube and each tube contains enough reagents to inactivate the heterophilic antibodies in 500 μl of sample material. The HBT also allows for the rapid and simple elimination of false positive heterophilic interference in plasma or serum for immunoassays (i.e., FSH, LH, Prolactin, TSH, Ferritin, CEA, AFP, hCG, HBsAg, CK-MB, CA 125, CA 19-9, NSE, etc.).
LI COR BIOTECH LLC Intercept (PBS) Protein-Free Blocking Buffer (500 mL)
Intercept (PBS) Protein-Free Blocking Buffers are formulated to provide highly efficient blocking and low background variability for replicable quantitative Western blots and other immunoassays. This buffer contains no proteins, for assays where use of animal-based products is prohibited. They are an excellent choice for biotin-streptavidin detection and suitable for a wide range of applications, including Western blots, In-Cell Western™ assays, and protein arrays. Intercept (PBS) Protein-Free Blocking Buffer is a ready-to-use blocker formulation in phosphate-buffered saline and is stored at 4 °C. It contains no sodium azide, making it suitable for both near-infrared or chemiluminescent detection.
LI COR BIOTECH LLC Intercept T20 (TBS) Antibody Diluent (3 x 500)
Intercept T20 (TBS) Antibody Diluent improves the specificity of the primary and secondary antibodies, reducing off-target effects. The diluent contains Intercept (TBS) Blocking Buffer in Tris-buffered saline (TBS) preformulated with Tween 20. Since there’s no need to mix the diluent yourself, it saves you time and reduces potential variation. Intercept T20 (TBS) Antibody Diluent contains a 0.05% concentration of Tween 20. It contains no sodium azide and is stored at 4 °C.
Boca Scientific Inc The Blocking Solution, 50ml
The Blocking Solution is a high-performance blocking reagent designed for saturating free binding sites on plastic surfaces or other protein binding surfaces and for minimizing nonspecific binding to surfaces in immunoassays. It is ideal for assays that require high reproducibility and low coefficients of variation, such as assays for pre-clinical and clinical studies, production of high quality diagnostics or measurement of precious specimens. The Blocking Solution is based on highly purified casein that has been chemically modified for maximum adsorption efficiency and a dense blocking layer. By incubating a surface with The Blocking Solution, such as a microtiter plate or western blotting membrane, free spaces on the surface are saturated by the components of this blocker. This minimizes unwanted binding of the analyte or the detection antibody to the surface, avoiding background and improving sensitivity of the assay.

Boston Bioproducts Inc Tris Buffered Saline-Tween, TBST (10X, with 0.5% Tween-20, pH 7.4) - 4x1L
10X Tris Buffered Saline - Tween (TBST) is a buffer-surfactant solution supporting a stable pH range between 7.4 and 8.0. When combined in a variable ratio, TBST is an effective wash buffer in Western blotting, in situ hybridization procedures, and immunohistochemistry staining, as it minimizes non specific binding of the materials without disrupting antigen-antibody binding. TBST is also used as an antibody diluent in immunoassays, and supports an array of molecular biology techniques.
Biogenex Laboratories Power Block
Power Block ™ reagent is a highly effective blocking reagent capable of reducing non-specific background staining associated with immunodetection techniques such as immunocytochemistry, ELISA, and Western blotting. Antibodies tend to bind non-specifically to membranes and tissues. To minimize this nonspecific binding, a blocking buffer is used to enhance signal-to noise ratio. Power Block™ reagent shows no cross-reactivity and it blocks more effectively than serum albumins. The blocking potency of Power Block™ reagent is superior to most other conventional formulations in producing a high signal-to-noise ratio. Power Block™ reagent may also be used as effective diluents for antibodies.""""
Research Products International Corp Casein Blocking Solution in TBS, 1 Liter
Contains 3% Casein in TBS buffer. Optimized for use in western blotting to minimize non-specific binding of antibodies.
Rockland Immunochemicals Blocking Buffer for Fluorescent Western Blotting 3-PACK (3 x 500 ml) - MB-070-003
Western Blot Blocking Solution is specifically designed for western blotting using fluorochrome conjugated antibodies. Pure nitrocellulose membrane is recommended for maximum performance. Other membranes, such as PVDF or nitrocellulose embedded in a support can be used, but may generate elevated backgrounds. Protein should be transferred from gel to membrane using standard protocols. Blocking buffer can be used for membrane blocking and to dilute both primary and secondary antibodies. Western Blot blocking buffer is suitable for use with fluorescent western blot imaging systems produced by Bio-Rad Laboratories, GE Healthcare, Alpha Innotech, FujiFilm Life Science, Licor Biosciences, UVP and Syngene.
Seracare Life Sciences Inc 10X TBS W/ 0 5% TWEEN 20(TBST)
10X Tris-buffered Saline (TBS) with 0.5% Tween 20 is used as a common Western blot wash solution and general wash buffer in immunoassay applications. Tween 20, a non-ionic detergent, reduces non-specific binding and protein-protein interaction during the wash step in immunoassay procedures.

Electron Microscopy Sciences Aurion Tween-20 10 ML
Tween-20 is a non-ionic detergent with a molecular weight of about 600 and a critical micelle concentration (CMC) of 0.06-0.07% in water at room temperature. Its working mechanism may in part be based on its action as a detergent, binding to the hydrophobic moieties of water insoluble compounds, rendering them hydrophilic. In addition, immuno-compounds may become incorporated into micelles when the Tween-20 concentration is higher than the CMC, for instance at 0.1 % in PBS at pH 7.4.
