When diluted in lysis buffer to a final concentration of 1X the Protease Inhibitor Cocktail prevents protein degradation by endogenous proteases present in whole cell extract. The 100X Protease Inhibitor Cocktail is a clear, colorless liquid.
Directions for Use
1. Briefly vortex the Protease Inhibitor Cocktail (100X) before use. 2. Just prior to lysing cells, dilute the cocktail 1:100 in desired lysis buffer to obtain a 1X working concentration.
Background
In order to study specific target proteins of interest protease-mediated degradation during the generation of protein lysates is to be avoided. A loss of normal cellular control occurs during cell lysis, and endogenous proteases within the cell extract are free to degrade proteins in an uncontrolled manner. The addition of protease inhibitors to the cell lysis buffer aids in the preservation of target proteins in the cell extract.
注意事项：
Storage: Store the undiluted 100X cocktail at 4ºC. Do not freeze.
