euchromatin

 [u-kro´mah-tin]
that state of chromatin in which it stains lightly, is genetically active, and is considered to be partially or fully uncoiled.

eu·chro·ma·tin

(yū-krō'mă-tin),
The parts of chromosomes that during interphase are uncoiled dispersed threads, and not stained by ordinary dyes; metabolically active, in contrast to the inert heterochromatin.

euchromatin

a chromosome material that stains heavily in METAPHASE but hardly at all in INTERPHASE when it is relatively uncoiled and undergoes TRANSCRIPTION. Compare HETERO CHROMATIN.

The intensity of Hoechst staining of DNA in compact chromatin regions, such as heterochromatin, is much more intense then Hoechst intercalated into looser regions of chromatin, such as euchromatin; therefore, the difference in Hoechst intensity can be used to determine the degree of compaction observed across nuclei (Belloc et al.
