Creatinine (Urinary) Colorimetric Assay Kit (10 Plates)

$997.00USD


Catalogue No. CRE-001-10P
Description Creatine synthesized in kidney, liver, and pancreas is transported in blood to muscle and brain where it is phosphorylated to phosphocreatine. Some free creatine in muscle is converted to creatinine. The amount of creatinine produced is proportional to the individuals muscle mass. In the absence of renal disease, the excretion rate of creatinine in an individual is relatively constant. Thus, urinary creatinine levels may be used as an index of standardization for other tests. Measurement of creatinine clearance is also useful in detecting renal disease and estimating the extent of impairment of renal function (1).

The Biosensis Creatinine (Urinary) Colorimetric Assay can be used to measure creatinine levels in urine. The assay relies on the Jaffe’ reaction, wherein a yellow/orange color forms when the metabolite is treated with alkaline picrate (2). The color derived from creatinine is then destroyed at acidic pH. The difference in color intensity measured at 500 nm before and after acidification is proportional to the creatinine concentration (1,3-4). The sample creatinine concentration is determined using a creatinine standard curve. The Creatinine (Urinary) Colorimetric Assay is not recommended for plasma or serum samples.

Assay precision has been determined to be 2.7% (intra-assay, n = 84) and 3.0% (inter-assay, n=5).

This assay kit has not been tested for other applications. It has been configured for research use only and is not to be used for diagnostic or clinical procedures.
