Vous avez recherché : Tampons
VWR propose un éventail de solutions tampons pour répondre aux besoins spécifiques des procédures chimiques et microbiologiques en laboratoires. Pour isoler et séparer les protéines lors du processus d'électrophorèse, l'utilisateur pourra sélectionner des tampons en poudre ou liquides qui protègent et suivent les échantillons protéiniques durant le process. Une large gamme de tampons de pH, de compositions et de formats différents est proposée pour la calibration et la normalisation des pH mètres. Pour la purification et la récupération des protéines dans des procédés de chromatographie, sélectionnez des tampons dans des formats adéquats aux procédures d’échange d’ions. La plupart des tampons sont disponibles en concentrés liquides, dans des bouteilles prêtes à l’emploi ou dans des formats déshydratés.

SSC buffer, 20X concentrate, pH 7,0
Supplier: Rockland Immunochemicals
Saline-sodium citrate (SSC) buffer is most commonly used as a buffer for the hybridisation process and washing in experiments where spcies of nucleic or ribonucleic acid are to be matched to complimentary sequences (such as Southern and Nouthern blotting, in situ hybridisation, or DNA microarrays). SSC is used to help control the stringency of hybridisation in these steps.

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.

SDS-Page running gel buffers, 10X concentrate
Supplier: Rockland Immunochemicals
SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, describes a technique widely used in biochemistry to separate proteins according to their electrophoretic mobility (a function of the length of a polypeptide chain and its charge) and no other physical feature. SDS is an anionic detergent applied to protein sample to linearise proteins and to impart a negative charge to linearised proteins.
