Quant-iT™ Protein Assay Kit, 500 Assays *0.25-5 µg* *for use with the Qubit™ fluorometer*

The Quant-iT™ Protein Assay Kit is designed specifically for use with the Qubit fluorometer Q32857, but may be used with any fluorometer or fluorescence plate reader. Using between 1 and 20 µl of your sample, this assay can quantitate samples ranging from 12.5 µg/ml to 5 mg/ml. It is ideal for quantitating protein samples for SDS-PAGE analysis, 2-D gels, Western blots or protein activity assays. The assay is accurate in the presence of reducing reagents, but not in the presence of a large amount of detergent. The 500-assay size is suitable for a typical biochemistry laboratory. Includes the Quant-iT™ protein reagent, premade calibration standards, and premade buffer. Reagent and buffer are designed for room temperature storage for the ultimate in convenience. The calibration standards should be stored at 4°C. Use with the Qubit fluorometer Q32857 for highest accuracy and speed. For higher-throughput applications using a microplate reader, use the 1000-assay size Q33210. Learn more at http://probes.invitrogen.com/products/qubit.
