关于本试剂盒
The Creatinine (Cr) ELISA quantitates Cr in serum, plasma and other biological fluids.
原理方法
The Competitive multispecies ELISA research use only kit is designed to quantitatively measure Creatinine (Cr) independent of species. A Cr standard is provided to generate a standard curve for the assay and all samples are read off a user generated standard curve.Standards or diluted samples are pipetted into a coated microtiter plate and Biotinylated Detection Ab specific to Cr is added. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each well and incubated. Then a TMB substrate solution is added to each well. The enzyme substrate reaction is terminated by the addition of stop solution and the color change is measured on a microplate reader. The concentration of Cr in the samples is then determined by comparing the OD of the samples to the standard curve.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

靶标信息
Creatinine is a nitrogenous waste molecule generated from muscle metabolism and is predominantly filtered through the kidneys to be excreted in urine. Although not directly encoded by a gene itself, its levels are significant for assessing kidney function, with serum creatinine being a key biomarker in nephrology. Creatinine evaluation serves as a primary tool for estimating the glomerular filtration rate (eGFR), offering an indirect measure of renal performance. Despite its prevalence in medical diagnostics, creatinine measurement has notable limitations due to its susceptibility to variations influenced by factors such as muscle mass, diet, age, and ethnicity, making it less reliable under certain conditions. Advanced methods now incorporate cystatin C alongside creatinine to enhance equation accuracy for eGFR estimations and mitigate racial biases in clinical settings. The metabolism of creatinine and its physiological significance underscores its utility as a cost-effective, accessible measure for kidney function, despite its shortcomings.
