Cystatin C ELISA
The K-ASSAY®Human Cystatin C ELISA is an enzyme immunoassay for the quantitative determination of human cystatin C in fluids and cell culture supernatants.
Cystatin C is a low molecular weight (approximately 13.3 kDa) plasma protein produced by all nucleated human cells that belongs to the type 2 cystatin protease inhibitor family. The kidney is the major site (>99%) of cystatin C clearance, predomantly via glomerular filtration and catabolism in the proximal tubule.
Serum Cystatin C has been proposed as an alternative marker of renal dysfunction to serum creatinine in patients with renal impairment, including diabetic nephropathy and chronic kidney disease. Serum Cystatin C levels rise in proportion to decreased glomerular filtration rate (GFR).
