Hi Dose this product P2714, include EDTA? what proteases do it inhibit? Thanks, Camilla
1 answer-
P2714 includes EDTA at 1 mM. The components of this mixture, such as AEBSF and aprotinin, act to inhibit serine proteases, including trypsin, chymotrypsin, and plasmin among others. Bestatin inhibits aminpeptidases. E-64 acts against cystein proteases. EDTA is an inhibitor of metalloproteases. Leupeptin acts against both serine and cystein proteases.

Wie löse ich das Pulver in 100 ml aqua dest???? Wie lagere ich das dann?
1 answer-
This product is packaged in a 10 mL serum vial with a crimp cap. Dissolve the contents of the vial in 10 mL of water or working buffer, then transfer to another container for dilution to 100 mL. Store the solution in working aliquots for at least 1 month -20 C, to avoid repeated freeze/thaw cycles. See the link below to review the product datasheet:

I intend on taking 1mL samples of blood to give serum and test hormone levels in these samples. Should I add the solubilised protease inhibitor cocktail (p2714) directly to the blood or after centrifugation (which could be a few hours later)?
1 answer-
A short delay may be negligible, however, it would not be detrimental to add protease inhibitors to whole blood samples if an extended delay is anticipated. This would ensure the best results. Please see the link below to review a publication of a similar nature:
