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™
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.

Protein extraction kit, bacterial PE LB™
Supplier: G-Biosciences
Bacterial PE LB™ kit has been developed for the extraction of biologically active soluble proteins, including recombinant proteins and inclusion bodies, from bacterial cells. Bacterial PE LB™ is a proprietary improvement on the lysozyme based lysis method, which allows extraction of soluble proteins and concurrent removal of nucleic acids (DNA and RNA) released during cell lysis. The Bacterial PE LB™ lysis system eliminates viscosity build-up, allowing effective clarification with lower centrifugal forces.

Cell culture salts, salt solutions and buffers
Supplier: Biowest
These irrigating buffers and salt solutions are sterile, physiological balanced solutions intended for use in the maintenance of mammalian cells, where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells in vitro. Applications include the intermediate steps for cultivation of cells, like washing, centrifugation, suspending and counting, as well as for many analytical methods or biochemical treatments. Principally these solutions should be used to keep the cells in suspension only for minutes or a few hours maximum. These buffers and solutions are not cell culture media.
