Native E.coli Sarcosine Oxidase

Cat No.
DIA-290
Description
Oxidoreductase that catalyzes the demethylation of sarcosine to glycine. Use Sarcosine Oxidase in your preferred creatinine reagent mix and rely on the proven diagnostic quality of this product.
Abbr
SAO, Native (E. coli)
Alias
SAO
Source
E. coli
Applications
Use Sarcosine Oxidase in diagnostic tests for the determination of creatinine. This can be done using one of two methods: (1) In combination with Creatinase and Creatininase. (2) In combination with Creatinine Deaminase, N-Carbamoylsarcosine Amidase and N-Methylhydantoinase (ATP-hydrolyzing).
