General description
SILu™Lite CST3 is a recombinant human protein expressed in E. coli. It consists of 120 amino acids, with a calculated molecular mass of 13.5 kDa. SILu™Lite CST3 is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.
Biochem/physiol Actions
Cystatin C is an inhibitor of cysteine proteases including cathepsin B (which has been identified as the most important ?-amyloid-degrading enzyme. Measurement of cystatin C in serum is replacing creatinine as an indicator of kidney function (glomerular filtration rate, GFR).
Physical form
Supplied as a lyophilized powder containing tris buffered saline and methionine.
