Pseudocolored photomicrograph of the synaptic region of fluorescently labeled living muscle fibers from the lumbricalis muscle of the adult frog Rana pipiens.

Pseudocolored photomicrograph of the synaptic region of fluorescently labeled living muscle fibers from the lumbricalis muscle of the adult frog Rana pipiens. Six hours after isolation of the muscle fibers, acetylcholine receptors were stained with red-fluorescent tetramethylrhodamine a-bungarotoxin (Cat. no. T1175) and myonuclei were stained with the green-fluorescent SYTO® 13 live-cell nucleic acid stain (Cat. no. S7575).
