Use this Dye Reagent Concentrate to refill the Bio-Rad Protein Assay, a simple, accurate method for total protein measurement. This colorimetric assay based on the Bradford method is compatible with many common lab reagents. Flexible assay formats: Use the standard assay for protein concentrations between 200 and 1,400 µg/ml (20-140 µg total protein) Use the low-concentration assay for.
All assays are easy to use, require little reagent preparation, and give accurate and reproducible results. * To adapt the RC DC assay to a microplate format, follow the micro test tube (microfuge tube) assay protocol in the RC DC instruction manual up to the centrifugation step where the supernatant is discarded. The pellet can then be transferred to the microplate, and the microplate assay.
The Bradford reagent is an acidified solution of Coomassie G-250; the dye is thus primarily protonated and red. The basis for the Bradford assay is that in order for the Coomassie dye to bind stably to protein, it needs to be doubly protonated. When the dye comes in contact with protein, the first electron is donated to charged groups on the protein. This disrupts the structure of the protein.

Use of Coomassie G-250 dye in a colorimetric reagent for the detection and quantitation of total protein was first described by Dr. Marion Bradford in 1976. In the acidic environment of the reagent, protein binds to the Coomassie dye. This results in a spectral shift from the reddish/brown form of the dye (absorbance maximum at 465 nm) to the blue form of the dye (absorbance maximum at 610 nm.

TRI Reagent® combines phenol and guanidine thiocyanate in a monophase solution to facilitate the immediate inhibition of RNase activity. Biological samples are homogenized or lysed in TRI Reagent®; the subsequent addition of bromochloropropane or chloroform results in the separation of the homogenate into aqueous and organic phases. RNA partitions to the aqueous phase, DNA to the interphase.
