AVAILABLE TO ORDER
GRADE & PURITY Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. Native ? Native grade — protein/biomolecule in its natural (non-recombinant, non-denatured) form. Use when native structure and activity are required. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. EnzymoPure™ ? EnzymoPure™ — Aladdin's line of high-quality enzymatic solutions. Use when enzyme purity and defined activity drive assay or process performance. ≥3 U/mg enzyme powder; from Aspergillus melleus

Overview

Proteinase is an enzyme used to break down proteins by hydrolyzing peptide bonds. Proteinase is used to degrade proteins, to study proteinase inhibitors and to study thermal inactivation kinetics. Proteinase is used in nucleic acid isolation procedures in incubations. It is used to study proteinase-activated receptors, such as the transducers of proteinase-mediated signaling in inflammation and the immune response. Product P755310 is from Aspergillus melleus and has been used to non-specifically degraded xylanase from Streptomyces halstedii.
