title: [Nomarski interference microscopy: use of combined contrast uranyl acetate-PTA for in vitro observation of monolayer cultures].
abstract: In this paper is reported a technique for the fixation and staining of cellular monolayers in vitro for observation by the interferential microscope according to Nomarski. This method includes the use of glutaraldehyde at 2.5% in phosphate buffer 0.1 M pH 7.5 and the sequential use of Uranil acetate (0.9% in absolute alcohol) and phosphtungstic acid (1% in absolute alcohol). This study has been conducted on 3 cellular lines: PC12 (rat pheocromocytoma), R.P.C. (rat pineal cells), primary culture obtained from a human carcinoma of the uterus.
