Cystatin C (Cys-C) Test Kit (FIA) 00031C

Product catalog summary

Overview of Cystatin C: Cystatin C is a small protein produced by all nucleated cells and found in various body fluids, including blood. It is filtered by the kidneys and broken down at a constant rate, making it a useful marker for evaluating kidney function.

Kidney Function and Cystatin C: Cystatin C is filtered by the glomeruli in the kidneys, which allow water, dissolved substances, and wastes to pass through while retaining larger proteins. The kidneys reabsorb cystatin C, glucose, and other substances from the filtrate, with the remaining fluid excreted as urine. Reabsorbed cystatin C is broken down and not returned to the blood.

Test Kit Specifications: The Cystatin C test kit includes a test cassette, extraction buffer, and a tip with fluorescent properties. It requires a sample volume of 5μL and has an assay time of 5 minutes. The working range is 0.5 to 10 mg/L, with a performance coefficient of variation (CV) of ≤15%. The kit should be stored at 2-30°C and has a shelf life of 18 months.

Ordering Information: The Cystatin C test kit (Cat # 00031C) is available in packs of 25 tests per box, with 20 boxes per carton. It is compatible with KS-001 and KS-002 Dry Fluorescent Immunoassay Analyzers from Beijing O&D Biotech Co., Ltd.

Compatible Instruments: The KS-001 and KS-002 analyzers have different specifications. KS-001 is a single-channel analyzer with a testing speed of 120 tests per hour in queuing mode, while KS-002 is a 12-channel analyzer with automatic testing capabilities. Both have a CV of ≤10% and include built-in thermal printers.

Technical Strengths: The test utilizes semi-liquid phase reaction and red nanofluorescent microsphere technology, enhancing sensitivity and accuracy. The fluorescent microspheres are stable under light and less affected by pH changes, providing consistent test results.

Additional Test Parameters: The document also lists various other tests available from O&D Biotech, including cardiac markers, diabetes-related tests, hormone levels, infection markers, and others, each with specific sample types, volumes, assay times, working ranges, and clinical references.

Cystatin C (Cys-C) Test Kit (FIA) 00031C-1

Cystatin C is a relatively small protein that is produced throughout the body by all cells that contain a nucleus and is found in a variety of body fluids, including the blood. It is produced, filtered from the blood by the kidneys, and broken down at a constant rate. This test measures the amount of cystatin C in blood to help evaluate kidney function. Cystatin C is filtered out of the blood by the glomeruli, clusters of tiny blood vessels in the kidneys that allow water, dissolved substances, and wastes to pass through their walls while retaining blood cells and larger proteins. What passes through the walls of the glomeruli forms a filtrate fluid. From this fluid, the kidneys reabsorb cystatin C, glucose, and other substances. The remaining fluid and wastes are carried to the bladder and excreted as urine. The reabsorbed cystatin C is then broken down and is not returned to the blood. Test cassette Extraction buffer

Cystatin C (Cys-C) Test Kit (FIA) 00031C-4

Technical Strength 1. Semi-Liquid Phase Reaction Half of the immune reaction is done in the liquid phase, which effectively improves the sensitivity and accuracy of the product. In the sample, the antigen binds more fully to the fluorescently labeled antibody. The release of fluorescent microspheres on the NC membrane is more uniform. Test results of whole blood samples have better repeatability. 2. Red Nanofluorescent Technology a. Comparing with ordinary fluorescein 1) FITC (fluorescein isothiocyanate) and other fluorescent substances are light sensitive and thus easily quenched. Their fluorescence...
