Product description

TBS Tween™20 is one of the most commonly used biological buffers for plate based immunoassays and Western blotting. It is isotonic, non-toxic to cells and contains a non-ionic detergent. It is used preferably as an antibody diluent and wash reagent in ELISA and Western blotting using alkaline phophatase or peroxidase-conjugated antibodies.

Medicago’s TBS-T buffer is supplied in exactly pre-weighed tablets, each tablet giving 500 ml of 0.15 M NaCl, 0.05% Tween^TM 20, 0.050 M Tris-HCl buffer solution with pH 7.6 at 25°C.

Applications

• Blocking buffer for plate based assays
• Wash buffer in immunoassays, for example ELISA and Western blotting

Directions for use

Deposit one tablet in a laboratory flask or beaker placed on a magnetic stirrer. Add 200 ml of deionized water and stir the solution for a few minutes. Adjust the volume up to 500 ml, stir until full dissolution and the buffer is ready to use.

Shipping and storage
