Cystatin SN/CST1, Human (HEK293, His)

Cystatin SN (CST1) is a component of human saliva that is immunologically similar to cystatin S but exhibits distinct specificity due to sequence variation. Cystatin SN has an isoelectric point of 7.5 and is a potent inhibitor of papain and dipeptidyl peptidase I, superior to Cystatin S in these activities. Cystatin SN/CST1 Protein, Human (HEK293, His) is the recombinant human-derived Cystatin SN/CST1 protein, expressed by HEK293 , with C-6*His labeled tag.
