Buffers, Dyes & Probes

Buffers
Almost all biological processes are pH-dependent. Even a slight change in pH can result in metabolic acidosis or alkalosis, resulting in severe complications. The purpose of a buffer in a biological system is to maintain intracellular and extracellular pH within a very narrow range and resist changes in pH in the presence of internal and external influences. Read the Background information to learn more about buffers and how they control hydrogen ion concentrations.

Dyes, Stains, and Probes
Cell visualization and microscopy are fundamental tools for investigating cellular behavior and structure, including changes in structural features, as well as cellular and sub-cellular dynamics under normal and pathological conditions. As the technology for microscopy has evolved, the ability to interrogate discrete protein and organelle dynamics has increased and the need for both general and specific visualization tools has grown. Dyes and stains provide rich information on cellular and subcellular processes, especially when used in conjunction with fluorescently-conjugated primary and secondary antibodies.

We are continuing to expand our line of OmniPur® and ULTROL® grade buffer materials, which are of superior quality and are manufactured to meet our stringent specifications. ULTROL® grade buffers, whenever possible, are screened for uniform particle size, giving uniform solubility characteristics. OmniPur® grade reagents are DNase, RNase, and protease tested to ensure the integrity of your starting material and to improve downstream results.
