[Histonet] euchromatin and heterochromatin

[Gudrun Lang]

Hi dear histonetters,

I have a question about chromatin and its stainability. Heterochromatin is
said to be the inactive part (perhaps hypermethylated) and the only part of
the chromatin, that can be stained. Euchromatin on the other side is the
active part and can't be stained.

The question is: What stain, what dye? Does this refer to hemalaun? Or to
the dyes, that are used for bandering the chromosomes (Giemsa, ..)?

Perhaps a silly question, but I hope, someone can help.
