cOmplete™, Mini Protease Inhibitor Cocktail
ROCHE/11836153001 - Tablets provided in a glass vial
Synonym: Protease inhibitor
Product Type: Chemical
cOmplete Mini
Inhibition of different proteases by cOmplete Protease Inhibitor Tablets One cOmplete, Mini tablet was added per 10 mL incubation solution. Proteolytic activity was determined with the Roche Universal Protease Substrate (casein, resorufin-labeled). When extractions or single-step isolations are necessary in the acid pH range, simply include pepstatin along with cOmplete, Mini tablets to ensure aspartic (acid) protease inhibition. All experiments were performed at +15 to +25 °C

| Application: | cOmplete™, Mini Protease Inhibitor Cocktail has been used as a component of • lysis buffer for lysing glioma tumor samples • radioimmunoprecipitatio • resuspension buffer for retinal ganglion cells homogenization |
| Application: | cOmplete™, Mini, is used for the inhibition of serine, cysteine, and metalloproteases in bacterial, mammalian, yeast, and plant cell extracts. cOmplete, Mini, contains both reversible and irreversible protease inhibitors. Therefore, we recommend the addition of cOmplete, Mini, to all stock buffers and solutions normally protected with protease inhibitors, and not just during the initial purification steps. cOmplete, Mini contains EDTA (1 tablet yields a 1 mM EDTA solution in 10 ml). Therefore, the extraction buffer should not contain divalent cations like Ca2+, Mg2+, or Mn2+, otherwise the inhibition of the metalloproteases might be incomplete. If the protein of interest will be purified by IMAC (Immobilized Metal Affinity Chromatography), for example, Poly-His-tagged recombinant proteins, EDTA has to be eliminated (e.g., by dialysis) prior to the chromatography. Alternatively, the product cOmplete, Mini EDTA-free, can be used. These tablets are identical to cOmplete, Mini, with the exception that no EDTA or other chelating agent is present. cOmplete, Mini Tablets, inhibit proteolytic activity in small extraction volumes (up to 10 ml). If you are working with a larger volume (up to 50 ml) we recommend to use a different cOmplete product. The composition of the cOmplete Tablet is identical to the cOmplete, Mini Tablet, therefore comparable results are achieved with both product types. |
| Components: | Proprietary mixture of several protease inhibitors with broad inhibitory specificity. |
| Features and Benefits: | Use cOmplete, Mini Protease Inhibitor Tablets to protect your proteins from a wide range of proteases. In just minutes, uninhibited proteolytic activity can degrade the protein you have spent days isolating. Each of these convenient water-soluble tablets contains a blend of protease inhibitors that inhibits proteolytic activity from most cell types, including animals, plants, yeast, and bacteria. No weighing or measuring is necessary, ensuring consistent results. • Easy-to-use: Simply drop a quick-dissolving tablet into your buffer. • Complete protection: Instantly protect your proteins against a broad range of proteases. • Flexible: Protect proteins in extracts from almost any tissue or cell, including animals, plants, yeast, bacteria, or fungi. • Safe: Choose non-toxic inhibitors that pose no risk to you or those around you. • Suitable for IMAC purification: Purify poly-histidine tagged proteins with cOmplete His-Tag Purification Resin. |
| General description: | cOmplete, Mini Protease Inhibitor Tablets, inhibit a broad spectrum of serine, cysteine, and metalloproteases, as well as calpains. Due to the optimized composition of the tablets, they show excellent inhibition effects, and are well suited for the protection of proteins isolated from animal tissues, plants, yeast, and bacteria. cOmplete, Mini Protease Inhibitor Tablets contain EDTA and both irreversible and reversible protease inhibitors. |

| Physical form: | Tablets in glass vials |
| Preparation Note: | Working concentration: 1 tablet per 10 ml extraction solution Working solution: Preparation of Working Solution One cOmplete Mini Protease Inhibitor Tablet is sufficient for the inhibition of the proteolytic activity in 10 ml extraction solution. When very high proteolytic activity is present, one tablet should be used for 7 ml extraction buffer. Tablets can be added directly to the extraction medium. Alternatively, a stock solution (7 X conc.) can be prepared. Stock solution (7 X conc.) Dissolve one cOmplete Mini tablet in 1.5 ml dist. water or in 1.5 ml 100 mM phosphate buffer, pH 7.0. Storage conditions (working solution): The stock solution can be stored at 2 to 8 °C for 1 to 2 weeks, or at least 12 weeks at -15 to -25 °C. |
| Quality: | Performance-tested with pancreas extract. |
| Reconstitution: | Soluble in aqueous buffers, or add directly to extraction media. Alternatively, prepare 7x stock solutions in 1.5 ml water or 100 mM phosphate buffer, pH 7.0. Stock solution is stable for 1-2 weeks at 2 to 8 °C or at least 12 weeks at -15 to -25 °C; can be used in thiol-containing solutions at 15 to 25 °C. |
| Specificity: | For the inhibition of serine, cysteine, and metalloproteases in bacterial, mammalian, yeast, and plant cell extracts. |
