FOCUS™ ProteaseARREST™ is a highly potent protease inhibitor designed for sensitive downstream proteomic analysis, including 2D and mass spec. The use of an alternative metalloprotease to EDTA allows for optimal action of nucleases to remove interfering nucleic acids and has an alternative to AEBSF (Pefabloc®) that has been shown to result in artifacts in mass spec. The 1X composition is 340µM AEBSF, 0.3µM Aprotinin, 1.45µM Bestatin, 3.4µM Calpain Inhibitor I, 5.25µM Leupeptin, 17µM Phosphoramidon and 1mM PMSF in DMSO. Supplied as a 100X DMSO solution in a 1ml vial.
