What is the solution stability of Cellulase, Product C1184?
Sigma-Aldrich has not determined the solution stability for this product. However, it is reported in Methods in Enzymology, 160, 264 (1988) that cellulase from Aspergillus niger is "completely stable over the range of pH 5.0-8.0 at 4°C for 24 hours and retains about 50% of its original activity after heating at 70°C for 10 minutes. The enzyme is completely inactivated by heating at 80°C for 10 minutes".
Are there any additives to Cellulase, Product C1184, in addition to the enzyme itself?
Per information from our supplier, maltodextrin is an extender in this product. Maltodextrin can vary in glucose chain lengths of 2-12. There can also be some free glucose in the product. Either sorbitol or propylene glycol is added to the product as a stabilizer during processing. These components may be "flashed off" during processing, but some small amount may still be present.
What is the molecular weight of Product C1184, Cellulase from Aspergillus niger?
The molecular weight is 26,000 Daltons.
