– Elastase that enhances insulin signaling and might have a physiologic role in cellular glucose metabolism. Circulates in plasma and reduces platelet hyperactivation, triggers both insulin secretion and degradation, and increases insulin sensitivity. CELA2A Protein, Human, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 27.9 kDa and the accession number is P08217.
