LICOR Intercept (TBS) Protein-Free Blocking Buffer (500 mL)
Intercept (TBS) Protein-Free Blocking Buffers are formulated to provide highly efficient blocking and low background variability for replicable quantitative Western blots and other immunoassays where animal-based products are prohibited. Intercept (TBS) Protein-Free Blocking Buffer is a ready-to-use blocker formulation in Tris-buffered saline (TBS). It contains no proteins, for assays where animal-based products are prohibited, it can be used with the widest range of targets for Western blot detection, it is ideal for primary antibodies that are optimized for Tris-based buffer systems, it can be used for detection of phosphorylated targets, it has superior performance for alkaline phosphatase detection, and it is an excellent choice for biotin-streptavidin detection. Intercept (TBS) Protein-Free Blocking Buffer is a ready-to-use blocker formulation in TBS and is stored at 4 °C. It contains no sodium azide, making it suitable for both near-infrared or chemiluminescent detection.
LICOR Intercept (TBS) Blocking Buffer (500 mL)
Intercept (TBS) Blocking Buffers are formulated to provide highly efficient blocking and low background variability for replicable quantitative Western blots and other immunoassays. Intercept (TBS) Blocking Buffer is a ready-to-use blocker formulation in Tris-buffered saline (TBS). It contains no mammalian proteins for the lowest cross-reactivity with mammalian antibodies; it can be used with the widest range of targets for Western blot detection; it is ideal for primary antibodies that are optimized for Tris-based buffer systems; it can be used for detection of phosphorylated targets; it has superior performance for alkaline phosphatase detection; it is an excellent choice for biotin-streptavidin detection.Shake well before each use.

Phosphate-buffered saline (PBS) is a salt solution that is commonly used in physiological and biochemical experiments. It can be used to maintain pH neutrality or to buffer against changes in pH in order to provide optimal conditions for cellular growth and function. The buffering range is between pH 6.8 and 7.4.
