QuantiChrom™ Protein Assay Kit
Protocol SDS  Printed Protocols and SDSs are not provided with kits.

Application
For quantitative determination of total protein.

Key Features
Sensitive and accurate. Use 10 mL samples. Detection range 0.06 - 1.0 mg /mL protein in 96-well plate assay.

Simple and high-throughput. The "mix-and-read" procedure involves addition of a single working reagent and reading the optical density. Can be readily automated as a high-throughput assay in 96-well plates for thousands of samples per day.

Low interference. Glucose, Tris, vitamins, and amino acids, DNA, RNA, salts, EDTA (
Versatility: assays can be executed in 96-well plate or cuvet.

More Details
The protein is known as the "building blocks of life" and is one of the most important macromolecules in life science. Proteins are polypeptides made up of amino acids and play various key roles in all aspects of biology. Protein quantitation is a very common practice for life scientists. Simple, direct and automation-ready procedures for measuring protein concentration are very desirable. BioAssay Systems QuantiChrom™ protein assay kit is based on an improved Coomassie Blue G method. The dye forms a blue complex specifically with protein, and the intensity of color, measured at 595nm, is directly proportional to the protein concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples and exhibits increased sensitivity towards peptides.

1. Your protein assay kit detection range is 60-1000 µg/ml, is it possible to improve the kit sensitivity?



Simply adding 50 μL sample to 200 μL reagent increases the sensitivity to 3-200 mg/mL protein.
