buffers

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.

Protein extraction reagents, BugBuster® and BugBuster® plus Benzonase®, Millipore®

Supplier: Merck Millipore (Novagen)

BugBuster® Protein Extraction reagent is formulated for the gentle disruption of the cell wall of E. coli, liberating soluble protein. It provides a simple, rapid, low-cost alternative to mechanical methods such as French Press or sonication for releasing expressed target protein in preparation for purification or other applications. The formulation utilises a detergent mix that is capable of cell wall perforation without denaturing soluble protein.
