Product Description


TBST buffer, namely TBS with Tween-20, is an isosmotic buffer salt solution commonly used in biology. Tris-HCl forms a stable pH buffer system, NaCl provides isosmotic conditions, Tween-20 as a detergent can increase the elution ability of buffer solution.It can be used to wash the non-specific bound antibodies and other reagents on the membrane in Western Blot experiments, as well as the preparation of blocking solution in immunofluorescence and immunohistochemistry experiments, the preparation of primary antibody or secondary antibody, and the washing of primary antibody or secondary antibody after incubation, so as to reduce the background and enhance the SNR. This product is a 10-fold concentrate, the main groups are 100 mM Tris, 1.5 mM NaCl, 1% Tween-20, need to be diluted 10 times before use.
