What is the difference between Protease Inhibitors P8849 and S8830?
P8849 is a DMSO solution and S8830 is a water soluble tablet. P8849 formulation is considered proprietary but does contain AEBSF, Pepstatin A, Bestatin, E-64, and Phosphoramidon. The formulation of S8830 also contains Aprotinin and Pepstatin A and the exact formulation is given on the product information sheet (under Documents, above).
Can Product No. P8849, Protease Inhibitor Cocktail, be used with with HIS-Select™ products or any other immobilized metal affinity chromatography (IMAC) products?
This product does not contain EDTA and can be used with sample processing by immobilized metal affinity chromatography (IMAC) suchas used for the purification of histidine-tagged proteins..
How should I dissolve Product No. S8830, SIGMAFAST™ Protease Inhibitor?
You can dissolve the product in 100 ml of water to make a 1X solution. You can make a 10X stock solution using 10 ml of water and then dilute 1:10 for use. Concentrations greater than 1X may appear slightly hazy. This will not affect the performance of the protease inhibitors.
Are there publications that cite use of Product S8830, SIGMAFAST™ Protease Inhibitor Cocktail Tablets?
Yes. Several examples of published papers that cite the use of Product S8830 include these:1. Smith, E.R., et al., Instability of fibroblast growth factor-23 (FGF-23): Implications for clinical studies. Clinica Chimica Acta, 412(11-12), 1008-1011 (2011). Use was with blood at 20 μL cocktail per 1 mL of blood.2. Reber, S., "Isolation of Centrosomes from Cultured Cells" (Chapter 8), from Microtubule Dynamics: Methods in Molecular Biology (Springer Protocols), vol. 777, pp. 107-116 (2011).
