Analytical biochemistry, 155(2), 270-274 (1986-06-01)
A method for the rapid staining of polypeptides in low-pH, urea-containing polyacrylamide gels is described. After 30 s of immersion in an alkaline solution of eosin Y, a variety of proteins stained with intensities similar to those seen with Coomassie

ACS applied materials & interfaces, 5(5), 1673-1680 (2013-02-07)
Interfacial visible light-mediated thiol-ene photoclick reactions were developed for preparing step-growth hydrogels with multilayer structures. The effect of a noncleavage type photoinitiator eosin-Y on visible-light-mediated thiol-ene photopolymerization was first characterized using in situ photorheometry, gel fraction, and equilibrium swelling ratio.
Han Shih et al.
Macromolecular rapid communications, 34(3), 269-273 (2013-02-07)
The utility of visible-light-mediated polymerization in tissue engineering has been limited due to the necessary use of potentially cytotoxic coinitiator and comonomer. Here, we report a visible-light-mediated thiol-ene hydrogelation scheme using eosin-Y as the only photoinitiator. Under visible light exposure

Males and females are in conflict over genetic transmission in the evolution of parthenogenesis, because it enhances female reproductive output but deprives the males' genetic contribution. For males, any trait that coerces females into sexual reproduction should increase their fitness.

Poultry science, 92(2), 331-338 (2013-01-10)
White striping is a condition in broiler chickens characterized grossly by the occurrence of white striations, seen parallel to the direction of muscle fibers, on broiler breast fillets and thighs. Based on visual evaluation of the intensity of white striping
