U heeft gezocht op: 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.

EDTA, 0.5M pH 8.0, Corning®

Catalogus nummer: (MDTC46-034-CI)
Leverancier: Corning
Omschrijving: EDTA (ethylenediaminetetraacetic acid) is a polyamino carboxylic acid. It is a colorless, water-soluble solid and is useful as a chelating agent due to its ability to "sequester" metal ions such as Ca2+ and Fe3+.  These cations are responsible for various undesirable effects in molecular biological and cell culture processes. After being bound by EDTA, these metal ions remain in the solution but exhibit diminished reactivity.  The use of EDTA therefore allows for greater control over many experiments.

Product Image-786-501

Solubilisation buffer, 2D-Xtract™

Catalogus nummer: (786-501)
Leverancier: G-Biosciences
Omschrijving: 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.
UOM: 1 * 50 mL
