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.

10% SDS (Sodium Dodecyl Sulfate), Corning®

Supplier: Corning

Sodium Dodecyl Sulfate (SDS) is an anionic detergent with applications in SDS-PAGE protein analysis and nucleic acid purification. It is a wetting agent that is effective in both acid and alkaline solutions, and is most often used as a protein and lipid solubilization reagent. SDS is also a powerful protein denaturant. This 10% solution is prepared in 18 megaohm water and is 0.2µm filtered.
