Pufry

Pufry odolávají změnám pH a chrání vzorky při přidání kyselin nebo zásad. Práškové a kapalné formy účinně sledují proteiny během elektroforézy, izolace a separace. Slané pufry lze také použít ke kalibraci a standardizaci pH metrů pro přesné měření. Blokovací látky zabraňují navázání protilátek na místa bez membrány, která by mohla vytvořit rušivé pozadí. Pufry mohou být k dispozici v různých koncentracích, aby vyhovovaly jakýmkoli potřebám, a to v kapalné nebo dehydratované formě.

Buffer, TBE solution 10X concentrate (TRIS-borate-EDTA buffer), Sigma-Aldrich®

Supplier: Merck

TBE (Tris/Borate/EDTA) Buffer is commonly used in nucleic acid electrophoresis. This solution is effective under slightly basic conditions, which keeps DNA deprotonated, water-soluble, and protected from degradation. This concentrate can be easily diluted to 1X or 0,5X before use (with molecular biology grade water).
