The Calcium concentration in most classical medium formulations, including RPMI, is sufficient to activate and/or stabilize α-Chymotrypsin.
α-Chymotrypsin calcium requirements:
Significant occupancy of Ca2+ site - approximately 0.1 mM
Saturating level - approximately 1 mM
Concentration for stock solution storage - 5–10 mM
