Abstract

A stable human serum based control for the assay of Total LD and CK and their isoenzymes. This control may be lyophilized and reconstituted and still provide the same enzyme activity prior to lyophilization, for seven (7) days after reconstitution, if stored in the dark at or about 2.degree.0 to 8.degree. C. No thiol compounds other than the amount normally used to purify CK isoenzymes are found in this highly stable control.
