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.

Blocking buffers, Protein-Free™
Supplier: G-Biosciences
Protein-Free™ Blocking buffer is a formulation of non-protein agents that eliminate non-specific binding sites in ELISA, blotting, immunohistochemistry and other applications. The absence of protein from the Protein-Free™ Blocking buffer eliminates problems associated with traditional protein based blockers, such as cross-reactivity and interference from glycosylated proteins.
