Descrizione generale

Mass spectrometry (MS) compatible protease inhibitor cocktail and phosphatase inhibitor cocktail, with broad specificity for the inhibition of:
  • Serine, cysteine and aspartic proteases, and metalloproteases
  • Tyrosine, serine/threonine, acid and alkaline phosphatases
All inhibitors and fillers were chosen so as not to interfere with LC-MS analyses. Any inhibitors capable of covalent, irreversible protein modification were avoided. This cocktail is EDTA-free. All inhibitors were selected to allow facile downstream sample processing, such as immobilized metal affinity chromatography (IMAC) for His-tagged protein purification and, uniquely, phosphopeptide enrichment.

Specificità

Protease inhibitors: serine, cysteine and aspartic proteases, and metalloproteases
Phosphatase inhibitors: tyrosine, serine/threonine, acid and alkaline phosphatases

Applicazioni

MS-SAFE Protease and Phosphatase Inhibitor has been used to measure ribosomal protein S6 kinase (S6K) activity.
Tested in mammalian cell lysates and liver tissue extracts. Designed for use in samples to be analyzed by mass spectrometry.

Caratteristiche e vantaggi

Comprehensive protease and phosphatase inhibitor cocktail for mass spectrometry analysis

Quantità

One vial makes 20 mL of 1× inhibitor cocktail working solution, using either water or extraction/lysis buffer. Alternatively, a 10× concentrated solution may be prepared by adding 2 mL of water or extraction/lysis buffer. This 10× solution may then be diluted 10-fold into extraction/lysis buffer as needed for a 1× working solution.

1-trans-Epoxysuccinyl-L-leucylamido(4-guanidino)butane (E-64) was shown to inhibit beta-trypsin by a reversible competitive mechanism; this contrasts with the widely held view that E-64 is a class-specific inhibitor of the cysteine proteinases and reports in the literature that it does not inhibit a
