Uric acid determination in biological samples such as cell culture media, biofluids (serum, urine), cell and tissue extracts. Sensitive. Use 10 µ L samples. Linear detection range: Colorimetric assay 15 – 1000 µ M Uric Acid. Fluorimetric assay 4 – 300 µ M Uric Acid. Fast. Run time is 30 minutes for Optical Density method and 10 minutes for Fluorimetric method for rapid results. Convenient. Room temperature “mix-and-read” procedure can be readily automated for high-throughput assay of thousands of samples per day. Method: OD570 or FL530/585nm; Samples: Biological samples such as cell culture media, biofluids (serum, urine), cell and tissue extracts
