Chymotrypsin C (CTRC)

Links to databases


CTRC (also known as Caldecrin) is a member of the peptidase S1 family of proteins. It regulates activation and degradation of trypsinogens and procarboxypeptidases,targeting specific cleavage sites within their zymogen precursors.Physiologically, CTRC reduces the levels of serum calcium. Suboptimal CTRC activity can predispose patients to pancreatitis, due to a reduction in normal protective trypsin-degrading functionality.

Chymotrypsin C (CTRC)


    • Within run precision Coefficient of Variation (CV)
    • 10%
    • Between run precision Coefficient of Variation (CV)
    • 10%

Precision (repeatability) is calculated from linearized NPX values over LOD.
