buffers

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.

Protein extraction kit, tissue PE LB™

Protein extraction kit, tissue PE LB™

Supplier: G-Biosciences

Tissue PE LB™ has been developed for extraction of total biologically active, soluble proteins from animal tissues. Tissue PE LB™ is based on an organic buffer and utilises a mild non-ionic detergent, chelating agent, and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. Depending on the required downstream application, additional agents such as reducing agents and protease inhibitors may be added into Tissue PE LB™. Tissue PE LB™ has been tested for use with a wide variety of fresh and frozen animal tissues.

Solubilisation buffer, 2D-Xtract™

Solubilisation buffer, 2D-Xtract™

Supplier: G-Biosciences

A protein solubilisation buffer for 2D analysis must solubilise proteins effectively, without disturbing the native charge of the proteins. Urea based solubilisation buffers solubilise proteins effectively, however can modify the native charge of the proteins, due to carbamylation. Urea exists in equilibrium with ammonium cyanate that modifies α- and ε-amino groups, inducing changes in the isoelectric point of proteins leading to artifactual results.
