[Product Name]

1. Common Name: Cystatin C Assay Kit

2. Abbreviative Name: Cys-C

[Intended Use]

Used to measurement of Cys-C concentration in human serum. Glomerular filtration rate (CFR) is the most direct indicator of kidney function tests. In the early kidney appeared to reduce the CFR. Cys-C is a low molecular weight cysteine protease inhibitors, Cys-C is almost completely filtrated by glomerular and reabsorbed by renal tubular. But can not be secreted nor excreted by renal tubular. Cys-C cannot be influenced by inflammation, gender, muscle and age changing. So Cys-C is a very stable sensitive indicator who can reflect glomerular filtration rate.

[Test Principle]

Latex-enhanced immunoturbidimetry with two point end assay. Cys-C and latex microsphere coated with Cys-C antibody occur agglutination reaction in the liquid phase of human serum. Which cause liquid turbidity change, using turbidimetric method to measure turbidity at 800/ 546 nm, with the presence of a certain amount of antibody, turbidity is proportional to the    Cys-C concentration.

[Reagent Composition]

R1. Glycine buffer.

R2. Latex particles coated with Cys-C human antibody 0.30 W / V%.


Applicable to multiple brands of automatic biochemical analyzer. For details, please refer to parameter table.
