Ecotin Protein, E. coli (His)
Based on 1 Customer Validation
Ecotin, a bacterial protein inhibitor, regulates serine proteases like trypsin and subtilisin. Ecotin's unique surface loop forms a stable complex, influencing enzymatic activity. Ecotin Protein, E. coli (His) is the recombinant E. coli-derived Ecotin protein, expressed by E. coli , with C-His labeled tag.
- Species: E.coli
- Source: E. coli

Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Biological Activity
Ecotin, a bacterial protein inhibitor, regulates serine proteases like trypsin and subtilisin. Ecotin's unique surface loop forms a stable complex, influencing enzymatic activity. Ecotin Protein, E. coli (His) is the recombinant E. coli-derived Ecotin protein, expressed by E. coli , with C-His labeled tag.
Ecotin is a protein inhibitor that regulates protease activity in bacteria. It specifically inhibits several serine proteases, including trypsin and subtilisin. This regulatory role allows bacteria to control protease-mediated processes, impacting various cellular functions. Ecotin's interaction with proteases involves a unique surface loop that forms a stable complex, influencing enzymatic activity. This protein plays a crucial role in bacterial physiology and is of interest in studying protease inhibition mechanisms.
Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2. The IC50 value is <1.4 nM.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of Tris and NaCl or 50 mM Tris-HCl, 300 mM NaCl, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
