General description
SIGMAFAST™ Protease Inhibitor Tablets are a water-soluble tablet formulation containing a broad-spectrum cocktail of protease inhibitors, including AEBSF, E-64, bestatin, leupeptin, aprotinin, and EDTA. One tablet can make 100 mL of cocktail and can inhibit proteases present in up to 20 g of cell extract.
The use of SIGMAFAST Protease Inhibitor Tablets is not advised with HIS-Select® products or other immobilized metal affinity chromatography (IMAC) products. These tablets contain EDTA, which is a metal chelator and can potentially remove metal ions from these affinity products.
Specificity
Inhibits serine, cysteine, aspartic, and metalloproteases.
Application
SIGMAFAST Protease Inhibitor Tablets has been used:
- to wash raw semen for membrane protein analysis
- in a solution to incubate CD4+ T cells to obtain total cell lysates for western blot analyses
- as a component of NP-40 buffer to homogenize the spinal cord tissue centered at the injury epicenter to conduct western blot analysis
- as a component in radio-immunoprecipitation assay (RIPA) buffer to homogenize the spinal cord tissue centered at the injury center to detect neuregulin-1 beta 1 (Nrg-1ß1) in spinal cord tissue samples with enzyme-linked immunosorbent assay (ELISA)
These tablets have been optimized and tested for general use. They have been used in various applications, including collecting tracheae in combination with ice-cold radioimmunoprecipitation assay buffer to determine the tracheal basal cell fate, and homogenizing rat lung tissues for western blot analysis.
Features and Benefits
- Broad-spectrum protease inhibition: inhibits serine, cysteine, aspartic, and metalloproteases, making it a versatile solution for protease inhibition in various applications.
- Water-soluble tablet formulation: easy to use and prepare, with one tablet making 100 mL of cocktail.
- Contains a cocktail of protease inhibitors: provides a comprehensive and effective solution for protease inhibition.
- Tested and optimized for general use: proven performance and reliability for a wide range of applications.
