Promoted negative staining of proteins in SDS-PAGE using Eosin B compounded with magnesium chloride.
Xu Wang et al.
Electrophoresis, 31(23-24), 3808-3815 (2010-11-17)
In this study, we describe an effective visualizing technique for proteins in SDS-PAGE based on the organic dye, Eosin B, the sensitivity of which can be further strengthened by the addition of magnesium to the staining solution after electrophoresis. The

Eosin B and eosin Y have been used to estimate micro- and submicrogram quantities of proteins respectively as shown in our previous reports. In the present study we describe the mechanism of eosin binding to proteins. At pH lower than

Protozoal parasites are unusual in that their thymidylate synthase (TS) and dihydrofolate reductase (DHFR) enzymes exist on a single polypeptide. In an effort to probe the possibility of substrate channeling between the TS and DHFR active sites and to identify

Self-assembling short peptides can offer an opportunity to make useful nano-/microstructures that find potential application in drug delivery. We report here the formation of multivesicular structures from self-assembling water-soluble synthetic amphiphilic dipeptides containing a glutamic acid residue at the C-terminus.

Among various dyes including congo red, thioflavin S, thioflavin T, eosin, rhodamine 6G, and phenol red, the eosin was the only dye that induced self-oligomerization of alpha-synuclein in the presence of a chemical coupling reagent of N-(ethoxycarbonyl)-2-ethoxy-1, 2-dihydroquinoline. To analyze
