Procion yellow

Procion Rubine MX-B, Procion Yellow H-A, and Turquoise MX-G. These dyes have found use over the last few decades in the purification of a broad range of proteins and enzymes, including albumin, decarboxylases, glycolytic enzymes, hydrolases, lyases, nucleases, oxidoreductases, synthetases, and transferases [77,78], The first use of dye-ligand affinity chromatography was described by Staal et al. in 1971 [79], Since that time, it has become an extremely popular tool for enzyme and protein purification, with hundreds of such compounds having been isolated by this technique [3-6,76-79],...

If cellulose dyed with Procion Yellow R be reduced, one-half of the molecule remains anchored to the fibre because it can be diazo-tized and coupled with phenol or an amine to produce a new dye and this operation can be repeated several times.

It has been found that many of the reactive dyes have not the highest degree of fastness to natural weathering. When exposed over prolonged periods to the atmosphere they fade more rapidly than normal laboratory fastness tests would predict. Procion Yellow H-A, Procion Yellow M-6G, Procion Yellow M-R, and Procion Yellow H-SG are all deemed to be of borderline fastness to weathering. They are, nevertheless, in many cases superior to vat dyes because they do not induce accelerated oxidation of the cellulose on exposure to light. The deeper the shade the less apparent is the alteration due to weathering.
