Description générale

Eosin Y, also known as Eosin yellowish is a widely used xanthene dye. It is a counterstain that is used to distinguish between various connective tissue fibers & matrices, and the cytoplasm of different types of cells. Eosin in combination with hematoxylin is useful to demonstrate the general histological architecture of a tissue.

Application

Eosin Y is suitable for use in hematoxylin and eosin (H&E) staining procedures for various tissue samples like lung nodule and kidney sections.

One of the principles underpinning our understanding of ageing is that DNA damage induces a stress response that shifts cellular resources from growth towards maintenance. A contrasting and seemingly irreconcilable view is that prompting growth of, for example, skeletal muscle

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
