this technique is useful with light and electron microscopic investigation for identifying and localizing potentially antigenic substances.

A

immunocytochemistry

17
Q

the preparation of biological materials for electron microscopy involves procedures similar to those described for the paraffin technique.

A

transmission electron microscopy

18
Q

this is used in histology and has a resolution limit of about 2200.

A

bright-field microscope

19
Q

this type of microscope uses an ultraviolet radiation source emitting wavelengths between 1000-3000 angstrom.

A

ultraviolet microscope

20
Q

this is visible light microscope uses an ultraviolet light source.

A

fluorescence microscope

21
Q

this is a modified bright-field microscope. the usual condenser is replaced by one that causes light to strike the image oblique angle.
