Soluzioni tampone

Resistendo alle variazioni di pH, i tamponi proteggono i campioni quando vengono aggiunti acidi o basi. Disponibili in polvere e in forma liquida, tracciano efficacemente le proteine durante l'isolamento e la separazione tramite elettroforesi. I tamponi salati possono anche essere utilizzati per calibrare e standardizzare i pHmetri per ottenere letture accurate. Le sostanze bloccanti impediscono l'adesione degli anticorpi ai siti liberi dalla membrana, che produrrebbero un background interferente. In varie concentrazioni per soddisfare qualsiasi esigenza, i tamponi possono essere disponibili in formato liquido o disidratato.

Buffer solutions

Supplier: Hanna

Solutions in sachets ensure optimum precision. The plastic-coated sachet provides a perfect liquid seal and good protection from light. The solutions should only be used once to avoid any danger of contamination. They also satisfy the requirements of the GLP and ISO standards. They have been adjusted using a pH meter that has been calibrated according to the NIST standards.
