buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

ELISA Wash Buffer (30X), Thermo Scientific

Supplier: Thermo Scientific

ELISA Wash Buffer is a Tris-based wash buffer for use in cytokine and other sandwich ELISA procedures. The buffer is the same formulation that is supplied with most Thermo Scientific Pierce ELISA Kits for cytokines and chemokines. The 30X concentrated stock solution is easily diluted 1:30 (vol:vol) in ultrapure water to yield sufficient wash buffer for a typical 96-well microplate ELISA protocol. Supplement an existing ELISA Kit or use as a convenient general purpose wash buffer for customized ELISA methods.
