Buffere

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.

10% SDS (Sodium Dodecyl Sulfate), Corning®

Supplier: Corning

Sodium Dodecyl Sulfate (SDS) is an anionic detergent with applications in SDS-PAGE protein analysis and nucleic acid purification. It is a wetting agent that is effective in both acid and alkaline solutions, and is most often used as a protein and lipid solubilization reagent. SDS is also a powerful protein denaturant. This 10% solution is prepared in 18 megaohm water and is 0.2µm filtered.
