Product details:
Creatine Assay Kit (Colorimetric/Fluorometric) (ab65339) provides an accurate, convenient measure of creatine in a variety of biological samples.
Creatine assay principle
In the creatine assay, creatine is enzymatically converted to sarcosine by creatinase. Sarcosine is then oxidized by sarcosine oxidase producing hydrogen peroxide. Hydrogen peroxide is then processed by a peroxidase causing a reaction with a probe to generate red color (λmax = 570 nm) and fluorescence (Ex/Em = 535/587 nm). Detection is by either colorimetric or fluorometric plate reader.
This is the same method used in the creatinine assay kit
ab65340
, except that this kit ab65339 does not include the initial creatininase enzyme step.
Creatine assay protocol summary
- add reaction mix to sample and standard wells
- incubate for 60 min
- analyze with a microplate reader

Other notes
This product was previously called K635 Biovision Creatine Colorimetric/Fluorometric Assay Kit. Biovision was acquired by Abcam in 2021.
Creatine is an endogenous compound whose function is to maintain a high ATP/ADP ratio, by way of its phosphorylated form and creatine kinase. Creatine supplementation has been used in the treatment of muscular, neurological and neurodegenerative diseases, as well as a sport performance enhancer. Detection of creatine level has wide applications in research and development.
