So PMSF is good for protecting soluble proteins like those in cytosol, QUOTE fred_33 @ Oct 18 2008, 05:55 PM PMSF is protease inhibitor, So it should be used as soon as possibly to avoid protease action, Basically protease are blocked in the cell endosomes of i’m not wrong,
PMSF is very unstable and must be added just prior to use, even if added previously, For the Protease Inhibitor Cocktail addition, we recommend Sigma Cat, no, P-2714, reconstituted according to the manufacturer’s instructions, and adding 250 μl per 5 ml Cell Extraction Buffer, The stability of protease inhibitor-supplemented Cell Extraction Buffer is 24 hours at 4°C,

Overview
How can I dissolve PMSF Protease inhibitor in lysis buffer?
During lysis, these are released and, in turn, can digest the target protein, Therefore, protease inhibitors are critical for preserving the target protein, Common protease inhibitors are PMSF phenylmethylsulfonyl fluoride, Aprotinin, Leupeptin, Pepstatin, and AEBSF-HCL 4-benzenesulfonyl fluoride hydrochloride, PMSF is highly effective and is the most popular choice for lysate preparation,

When to use PMSF in a cell lysis buffer?
6 Resuspendre les corps d’inclusion dans le tampon d’extraction Utiliser assez de tampon pour obtenir une concentration finale en protéine de 1 mg/mL Ajouter 10 uL PMSF 100 mM par mL de solution Incuber une heure à T/P 7 Diluer la solution dix fois avec le tampon d’extraction et dialyser toute la nuit contre 100 volumess de solution de lavage,
Pourquoi le PMSF est-il si important ? L’activité des protéases est étroitement régulée dans tous les organismes, Toutefois, ce contrôle strict est perturbé par la lyse cellulaire, Lors de l’extraction et de l’isolement des protéines hors des cellules, il est nécessaire d’éviter la dégradation des protéines cibles, C’est là que le PMSF de grade BPF entre en jeu en tant qu’inhibiteur de la protéase, ce qui permet la …
