In histology, this task is often performed on tissue sections prepared with FFPE. For 10 points each:
[10m] Name this task, types of which involve heavy metals for subsequent electron microscopy, immunohistochemistry for distinguishing antigens, and hema·to·xylin and eosin for distinguishing cellular features.
ANSWER: staining [accept immunostaining]
[10h] FFPE sections are typically prepared with these devices that slice samples into thin pieces. Femtosecond lasers can replace mechanical blades in these devices.
ANSWER: microtomes [accept laser microtomes]
[10e] FFPE tissue samples are fixed with formalin, which is a four-percent solution of this compound. This simplest aldehyde is used to preserve cadavers.
