Flow Cytometric Analysis of Feline Reticulocytes

Flow cytometric DNA ploidy analysis of feline mammary tumors.

Flow cytometric DNA analysis was performed on biopsies from 9 nonmalignant and 111 malignant (primary and metastatic) feline mammary lesions. In our series, 46.3% of the primary mammary carcinomas appeared to be aneuploid, whereas all but one benign breast lesion were diploid. The degree of aneuploidy in carcinomas was low, with a relatively high number of primary tumors (12 of 82) displaying h...

Flow cytometric analysis of normal human megakaryocytes.

Megakaryocytes from normal routine human bone marrow aspirates were analyzed by flow cytometry for size, fine cell structure and granularity, membrane expression of glycoprotein (GP) IIb/IIIa and ploidy. Marrow cells were initially enriched for megakaryocytes by a Percoll density gradient and megakaryocytes were labeled with a fluoresceinated monoclonal antibody directed to the GPIIb/IIIa compl...

Automated flow cytometric analysis of cerebrospinal fluid.

BACKGROUND Recently, the UF-100 (Sysmex Corporation) flow cytometer was developed to automate urinalysis. We evaluated the use of flow cytometry in the analysis of cerebrospinal fluid (CSF). METHODS UF-100 data were correlated with microscopy and biochemical data for 256 CSF samples. Microbiological analysis was performed in 144 suspected cases of meningitis. RESULTS Good agreement was obta...

Flow cytometric analysis of chlorhexidine action

Flow cytometric analysis of chlorhexidine action.

The mechanism by which chlorhexidine kills bacteria is still ill defined. We have investigated the action of chlorhexidine on Escherichia coli JM101/psb311 using a combination of flow cytometry and traditional methods. Chlorhexidine-induced uptake by E. coli cells of bis-(1,3-dibutylbarturic acid) trimethine oxonol and propidium iodide, which monitor membrane potential and membrane integrity re...
