![Creatinine Assay Kit (Colorimetric) [NBP3-07134] - Conversion of creatine and p-creatine to creatinine. Creatine and p-creatine are converted non-enzymatically to the metabolite creatinine, which diffuses into the blood and is excreted by the kidneys. In vivo, this conversion appears to be irreversible and in vitro it is favored by higher temperatures and lower pH. Creatinine forms spontaneously from p-creatine.](http://images.novusbio.com/fullsize/Creatinine-Assay-Kit-Colorimetric-Product-Image-NBP3-07134-img0003.jpg)
