1973Trans. Amer. Microsc. Soc. XCII. 417 We examined the utility of acridine orange staining and epifluorescence microscopy..as a method for estimating bacterial numbers in natural waters. 1987Nature 23 Apr. 791/1 Almost all the chloroplasts in the ciliates displayed red epifluorescence, which indicates that they contained chlorophyll a but not phycoerythrin. 1988Blood LXXII. 1393 Epifluorescence video microscopy coupled with digital image processing techniques..were used to analyse..the effect of one of the most potent carbamoylpiperidine congeners..on platelet accumulation at a collagen-coated surface.

1973Trans. Amer. Microsc. Soc. XCII. 418 Figure 1 shows the appearance of a typical field of an acridine orange-stained sample from natural water under epifluorescent illumination using a 40 × objective. 1988Jrnl. Appl. Bacteriol. LXIV. 329/2 The method proposed in this paper to aid the detection of irradiated food is a combination of the Direct Epifluorescent Filter Technique..described by Pettipher et al..and a total aerobic plate count. |
