  1. How much of Product P2714, Protease Inhibitor Cocktail, needs to be used in cell lysates?

    One bottle is recommended for the inhibition of proteases present in a maximum of 20 grams of cell extract.

  2. How should I dissolve and store Product P2714, Protease Inhibitor Cocktail?

    You can dissolve the product in 10 ml of water to make a 10X stock solution and then dilute 1:10 for use.  Aliquots can be stored at -20 C for 1 month.

  3. How much of Product P2714, Protease Inhibitor Cocktail, should I use with serum? 

    Dilute the contents of the vial in 10 mL of water, yielding a 10X initial concentration . Then dilute the stock 1:10 in the serum (1 part of inhibitor solution to 10 parts of serum). This would be a 1:100 dilution (containing the concentrations of each inhibitor as listed on the data sheet) in the serum. This is true for most cell lysates, serum, and culture media.

  4. Can Product P2714, Protease Inhibitor Cocktail, be used with ELISA?

    Yes, because it is water based.

  5. Can Product P2714, Protease Inhibitor Cocktail,be used with Nickel columns?

    No because it contains EDTA.

  6. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.
