Creatinine is a byproduct of creatine that is produced in the muscles and removed from the body by the kidneys. Measuring the amount of creatinine in the blood and/or urine can predict how well the kidneys are working. Immunoassay is a general method of detecting creatinine. However, since creatinine is a very small molecule it is generally very difficult to generate an antibody that binds strongly to the protein for detection. CellMosaic’s BSA-creatinine conjugate is designed with a flexible linker of optimal length (8-atom length, L8) and a labeling chemistry that does not interfere with creatinine binding. Each lot of the conjugate consists of an optimally loaded BSA (5-10 creatinine molecules per BSA molecule as determined by mass spectrometry or SEC HPLC).nnThe product is sold as either 1 vial of 1 mg (Cat# CM52117-1MG) or 5 vials of 1 mg (Cat# CM52117-5MG).
