A diagnostic strip for determining the amount of sarcosine, creatinine and hydrogen peroxide in a biological or environmental sample

摘要

The present invention relates to a diagnostic strip for enzymatic assay for determining the amount of sarcosine and creatinine based on the resulting hydrogen peroxide in a biological sample or in an environmental sample with the possibility of visual electronic evaluation by evaluating the intensity of the color reaction product. Absorbent matrix zones are applied to the diagnostic strip, where the first sarcosine reaction zone comprises sarcosine oxidase, 3- (N-ethyl-3-methylanilino) propanesulfonic acid sodium salt, and phenol, and the second reaction zone contains peroxidase and 4-amino-2. Or 3-dimethyl-1-phenyl-3-pyrazole, or the band in the reaction zone may contain 3,3-diaminobenzidine, o-phenyldiamine or the ammonium salt of 2,2'-azino-bis (3-ethylbenzothiazolin-6) sulfonic acid.
