buffers
Résistant aux variations de pH, les tampons protègent les échantillons lors de l'ajout d'acides ou de bases. Disponibles sous forme de poudre ou de liquide, ils permettent un suivi efficace des protéines pendant l'électrophorèse et leur séparation. Les tampons salins peuvent également servir à calibrer et à standardiser les pH-mètres pour des mesures précises. Les substances bloquantes empêchent la fixation des anticorps aux sites libres de la membrane, évitant ainsi un bruit de fond parasite. Proposés à différentes concentrations pour répondre à tous les besoins, les tampons sont disponibles sous forme liquide ou déshydratée.

Nuclear and cytoplasmic extraction reagents, NE-PER
Supplier: Thermo Fisher Scientific
The NE-PER Nuclear and Cytoplasmic Extraction Kit provides for efficient cell lysis and extraction of separate cytoplasmic and nuclear protein fractions in less than two hours. The nuclear protein extraction method involves simple, stepwise lysis of cells and centrifugal isolation of nuclear and cytoplasmic protein fractions. A benchtop microcentrifuge, tubes and pipettors are the only tools required. The NE-PER Reagents efficiently solubilise and separate cytoplasmic and nuclear proteins into fractions with minimal cross-contamination or interference from genomic DNA and mRNA. The isolated proteins can be used to perform immunoassays as well as protein interaction studies such as mobility shift assays (EMSA), co-immunoprecipitation (Co-IP) and pull-down assays.
