Creatinine chemistry reagents, R1: 60ml×2 R2: 15ml×2

A liquid-stable, two-reagent enzymatic kit for the determination of creatinine in serum, plasma, or urine using the sarcosine oxidase method. Creatinine is converted through creatininase, creatinase, and sarcosine oxidase to generate hydrogen peroxide, which is coupled via peroxidase to a stable chromogen for colorimetric measurement. The enzymatic approach offers improved specificity over Jaffe chemistries, with reduced interference from bilirubin, ketones, and common drugs. Each lot is validated for linearity and calibration stability across the measuring range. Supplied with R1 (60 mL × 2) and R2 (15 mL × 2).
