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.

Optimizer Buffer™ for optimal cross-linking and modification
Supplier: G-Biosciences
The conjugation and modification reactions used to cross-link proteins or couple labels to proteins, such as biotin, enzymes, and fluorescent dyes, require certain conditions, including pH and chemical composition for optimal conjugation. Many common buffers routinely used in laboratories have an inhibitory effect on conjugation reactions; for example, Tris buffers inhibit coupling to amines.

Blocking buffers, Protein-Free™
Supplier: G-Biosciences
Protein-Free™ Blocking buffer is a formulation of non-protein agents that eliminate non-specific binding sites in ELISA, blotting, immunohistochemistry and other applications. The absence of protein from the Protein-Free™ Blocking buffer eliminates problems associated with traditional protein based blockers, such as cross-reactivity and interference from glycosylated proteins.
