Flow-cytometric enumeration of reticulocytes with the new fluorochrome 1′,3′-diethyl-4,2′-quinolylthiacyanine
1992
Several flow-cytometric methods for reticulocyte enumeration in whole blood have been developed, with different degrees of practical use. Recently, a new fluorochrome, 1′,3′-diethyl-4,2′-quinolylthyacianine (DEQTC) was proposed in a brief report, as an alternative to thiazole orange for reticulocyte counting. We have evaluated the usefulness of this fluorescent stain by assessing the optimal conditions for the flow-cytometric analysis, and by comparing in double-blind assays the quantitative results of this technique with those obtained by manual counting with brilliant cresyl blue. Our results show that flow cytometry with DEQTC is highly correlated to the manual method (r=0.95–0.99), supp…
Lysosome-like particles in Geotrichum candidum : A cytochemical study
1971
Lysosome-like particles were localized in Geotrichum candidum by means of the technique for the detection of acid phosphatase of PEARSE and staining with the vital dyes Brilliant cresyl blue and Neutral red. Pretreatments of the cells with procedures injuring the lysosome membrane resulted in shortening of the incubation time (2 min instead of 30 min). After exposure to 1% Triton X-100 the cells showed uniform strong staining due to the release of the enzyme into the cytoplasm.
