Tissue/cell processing and embedding Tissue slide sectioning H&E staining Special stains including: PAS, ORO, Trichrome, VVG for elastin, Giemsa Sectioning of thick tissue curls or core punches for ...

In contrast, less condensed chromatin—which tends to be GC-rich and more transcriptionally active—incorporates less Giemsa stain, and these regions appear as light bands in G-banding.

Regions are identified by the specific morphological features that are consistently found in a chromosome, such as the presence of prominent Giemsa-staining bands. The regions are named p1 ...
