buffers
Buffere modstår pH-ændringer og beskytter prøver, når der tilsættes syrer eller baser. Pulver- og flydende former sporer effektivt proteiner under elektroforeseisolering og -separation. Saltbufferne kan også bruges til at kalibrere og standardisere pH-metre for nøjagtige aflæsninger. Blokerende stoffer forhindrer antistofbinding til membranfri steder, der ville producere en interfererende baggrund. Buffere kan fås i flydende eller dehydrerede formater i forskellige koncentrationer, der passer til ethvert behov.
