Protein Method Blocking Buffers
Surmodics Inc Phosphate Buffered Saline/Casein Block & Diluent-5X, 1L
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.
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.).
SCANTIBODIES LABORATORY INC HBR 1, PURIFIED (3KC533) 500MG
The 3KC533 Heterophilic Blocking Reagent 1, Purified from Scantibodies Laboratory, Inc. contains specific murine immunoglobulins that block the heterophilic interaction by active binding to the heterophilic antibodies, which are capable of cross-linking the capture and the detection antibodies used in the immunoassay, resulting in false positive readings. The attachment of HBR-1 to the heterophilic antibodies blocks this cross-linking, and eliminates the interference caused by the heterophilic antibodies in the humoral fluids. In addition to its active blocking, this product is also characteristic of its passive blockage of the heterophilic interaction as well. The HBR is a liquid reagent with a protein concentration of 20 ± 2 mg/ml. The immunoglobulins are dissolved in a phosphate buffer with a pH of 7.2-7.6. The immunoglobulins in this product are at a purity of greater than or equal to 95%.
Boca Scientific Inc The Blocking Solution, 500ml
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.
LICOR 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.
LICOR Intercept T20 (PBS) Antibody Diluent (500 mL)
Intercept T20 (PBS) Antibody Diluent improves the specificity of the primary and secondary antibodies, reducing off-target effects.The diluent contains Intercept (PBS) Blocking Buffer preformulated with Tween 20 for use in a phosphate-buffered saline (PBS) system. Since there’s no need to mix the diluent yourself, it saves you time and reduces potential variation. Intercept T20 (PBS) Antibody Diluent contains a 0.05% concentration of Tween 20. It contains no sodium azide and is stored at 4 °C.
Surmodics Inc StabilBlock Immunoassay Stabilizer 50ml
StabilBlock™ Immunoassay Stabilizer effectively preserves the conformation and activity of dried proteins while simultaneously blocking the surface to reduce non-specific binding. It can be used to stabilize antibodies, antigens or enzymes on an assortment of immunoassay components including polystyrene plates, tubes, glass, membranes, and filter paper. The key benefits are reduction of non-specific binding while increasing signal-to-noise ratios within immunoassay applications.
LICOR TBS Blocking Buffer and PVDF Kits (single buffer kit)
The non-mammalian Intercept Blocker in these kits is in TBS (Tris-buffered saline) containing 0.06% Kathon II. The Immobilon-FL PVDF membrane included in these kits has been tested to ensure a low background for infrared Western blot success. This kit contains Intercept (TBS) Blocking Buffer (500 mL) and Millipore Immobilon-FL PVDF Membrane (1 roll; 0.45µm, 26.5 cm x 3.75 m).
