BSA Tween 20 Blocking Solution in TBS is a ready-to-use solution designed for protein blocking in various immunological assays, including ELISA, Western Blot, and immunohistochemistry. This solution contains bovine serum albumin (BSA) in a Tris-buffered saline (TBS) with Tween 20, which prevents non-specific binding by blocking available sites on the surface of membranes or other solid phases. It ensures that antibodies or proteins of interest bind specifically to their targets during assays, thereby increasing the sensitivity and accuracy of results. The 500-milliliter bottle offers a convenient volume for routine laboratory use.
