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.

VWR®, pH electrode maintenance kit

Supplier: VWR Chemicals

The measurement of the pH value is one of the most frequently and universally made measurements in science.

What is often not fully understood is the fact that a large number of problems related to pH measurement is the
correct selection, care or maintenance of the electrodes with particular emphasis on the reference electrode.

Phosphate Buffered Saline with 0,05% TWEEN® 20, pH 7,4

Supplier: Merck

Phosphate buffered saline with 0,05% Tween® 20 or PBST contains PBS buffer with a low-concentration of Tween® detergent. It is a common wash buffer and due to the presence of detergent, it can easily remove or block excess components thus reducing foaming and non-specific binding on the membrane and microtiter plate wells.
