Buffers

Buffers zijn bestand tegen pH-veranderingen en beschermen monsters wanneer zuren of basen worden toegevoegd. Zowel in poeder- als vloeibare vorm zijn ze geschikt voor het efficiënt volgen van eiwitten tijdens elektroforetische isolatie en scheiding. De zoute buffers kunnen ook worden gebruikt om pH-meters te kalibreren en te standaardiseren voor nauwkeurige metingen. Blokkerende stoffen voorkomen de hechting van antilichamen aan membraanvrije plaatsen die een storende achtergrond zouden veroorzaken. De buffers zijn verkrijgbaar in verschillende concentraties, voor elke toepassing, en kunnen vloeibaar of gedehydrateerd zijn.
