STABILIZATION OF CREATININE KINASE AND PRODUCTION OF REFERENCE AND STANDARD SERUMS FOR CREATININE KINASE AND SAIDSERUMS

摘要

To stabilise creatine kinase by disulphide modification, creatine kinase is mixed in any desired sequence a) with a molar excess of disulphide such as cystine, homocystine, cystine methyl ester and/or cystamine and/or thiosulphonate such as S-methyl methanethiosulphonate and b) with a molar excess of water-soluble carbohydrate as carrier.
