Immunoperoxidase stain with hematoxylin counterstain; original magnification x200.

Luxol fast blue and cresyl violet were used to counterstain the nerve and DRG sections, respectively.

Sodium-potassium ATPase served as a counterstain for cell basolateral membranes (Molitoris et al., 1992; Secker et al., 2017).

Following exposure to the horseradish peroxidase-conjugated streptavidin substrate, positive immunoreactivity (brown precipitate) was detected using the Vectastain Elite DAB kit (Vector Laboratories, USA) and hematoxylin (Biocare Medical, Pacheco, CA, USA) was used for a nuclear counterstain.

Gonads were embedded in paraffin, sections cut at 5 [micro]m and stained with Harris hematoxylin followed by eosin counterstain (Presnell & Schreibman 1997).

Adipogenesis differentiation was evaluated by Oil Red O staining (red) and hematoxylin counterstain (blue), and the yellowish lipid depositions were observed in the differentiated cells.

Enhancement of histological detail using metanil yellow as counterstain in periodic acid/Schiff' s hematoxylin staining of glycol methacrytlate tissue sections.
