Sigma Aldrich Fine Chemicals Biosciences COMPLETE ULTRA TABLETS MINI Protease Inhibitor Cocktail Tablets | N/A | Tablets
COMPLETE ULTRA TABLETS MINI protease inhibitor cocktail tablets | Purity: N/A | Mol Wt: N/A | CAS No: N/A | MFCD: N/A | Unit of Measure: TabletsThese protease inhibitor tablets contain a broad spectrum mix of inhibitors that target serine, cysteine, aspartic and metalloproteases. EDTA is also included to enhance protease inhibitor efficiency. The mini tablet format in foil blister packs protects proteins from degradation during handling. When added to lysis buffers, COMPLETE ULTRA TABLETS MINI effectively protect intact proteins from degradation during extraction and purification procedures like radioimmunoprecipitation and general protein purification. By preventing protease activity, COMPLETE ULTRA TABLETS MINI help ensure proteins are not damaged or degraded before analysis.
