Creatinine Assay Kit ab65340 provides an accurate, convenient measure of creatinine concentration in biological fluids such as serum, urine or CSF.
In the creatinine assay protocol, creatinine is converted to creatine by creatininase, creatine is converted to sarcosine, which is specifically oxidized to produce a product which reacts with a probe to generate red color (λmax = 570 nm) and fluorescence (Ex/Em = 538/587 nm).
Unlike picric acid assays, this kit is suitable for serum creatinine determinations, as well as for urine and other biological samples.
Creatinine assay protocol summary:
- add samples and standards to wells
- add reaction mix and incubate for 60 min at 37°C
- analyze with microplate reader
For deproteinization of samples: Better results are typically seen with this assay when using a 10kda filter for sample deproteinization than when using the PCA method.
This product is manufactured by BioVision, an Abcam company and was previously called K625 Creatinine Colorimetric/Fluorometric Assay Kit. K625-100 is the same size as the 100 test size of ab65340.
In the human body creatinine plays an integral role in reflecting muscle metabolism rates and biochemical balance. Creatinine levels aid in assessing glomerular filtration rate (GFR) an important measure of kidney function. It is not part of a protein complex as it results from muscle activity. Its levels in blood and urine help calculate the protein to creatinine ratio providing insights into renal health. The constant exchange and excretion of creatinine make it a reliable biomarker in metabolism studies.
Creatinine also known as 2-amino-1-methyl-5H-imidazol-4-one is a small molecule with a molecular mass of approximately 113.12 g/mol. Its mechanical functions stem from its role as a breakdown product of creatine phosphate primarily in muscle. Creatinine serves as a marker for kidney function due to its constant production and relatively stable concentration in the blood. It gets filtered out of the blood by the kidneys and is present in urine. Laboratories focus on measuring creatinine levels using tools like the creatinine assay kit and creatinine test kit to evaluate renal function.
Muscle metabolism and kidney filtration both involve creatinine's function. Creatinine formation and elimination connect to pathways that maintain homeostasis and waste removal. Key proteins in these pathways include creatine kinase which catalyzes the conversion of creatine to creatine phosphate. The creatinine protein ratio becomes relevant in evaluating proteinuria a condition where excess protein is present in urine indicating possible kidney dysfunction.
Kidney-related conditions and muscle disorders often involve creatinine. Common health concerns like chronic kidney disease (CKD) associate with elevated creatinine levels indicating reduced kidney function. Additionally conditions such as muscular dystrophy can alter muscle creatinine levels. These diseases relate to proteins such as nephrin involved in the kidney filtration barrier and dystrophin essential for muscular integrity. For clinical assessments tools like the creatinine assay and understanding the protein creatinine ratio are key for early detection and management.

Terms & Conditions.
Mice were injected i.p. with 6-ECDCA before I/R injury. At 24 h after I/R, kidney, serum and urine samples were collected for measurements of creatinine in serum with ab65340
Standard curve: mean of duplicates (+/- SD) with background reads subtracted
Standard curve: mean of duplicates (+/- SD) with background reads subtracted
Creatinine measured in mouse and human serum plotted against RFU. Samples were diluted 5-10 fold.
Creatinine measured in mouse and human urine plotted against RFU. Samples were diluted 400-800 fold.
Creatinine levels in filtered human urine was measured in the presence or absence of creatininase (background signal subtracted.
