Mouse C3H10T1/2 fibroblasts are multipotent, mesenchymal stem cell (MSC)-like progenitor cells that are widely used in musculoskeletal research. In this study, we have established a clonal population of C3H10T1/2 cells stably-transfected with mRuby2, an orange-red fluorescence reporter gene. Flow cytometry analysis and fluorescence imaging confirmed successful transfection of these cells. Cell ...

We investigated the accuracy and precision of flow cytometric (FCM) estimates of bacterial abundances using 4', 6-diamidino-2-phenylindole (DAPI) and Hoechst 33342 (HO342, a bisbenzamide derivative) on paraformaldehyde-fixed seawater samples collected from two stations near Oahu, Hawaii. The accuracy of FCM estimates was assessed against direct counts by using epifluorescence microscopy. DAPI a...

We assessed the utility of using a p63/a-methylacyl-coenzyme-A racemase (AMACR) antibody cocktail on destained H&E-stained sections. We transferred 61 stored (7-11 months old) and 10 recent (<1 month old) H&E-stained sections of prostate needle biopsy tissues to charged slides and subsequently stained them with a p63/AMACR immunohistochemical antibody cocktail. The AMACR and p63 staining intens...

We have developed a new and simple flow cytometric method to detect damaged red blood cells (RBCs) using anti-Hb in hypotonic solution. We studied a total of 200 patients, including 62 patients with schistocytosis, 8 postsplenectomy patients, and 108 healthy controls. Peripheral blood (2 microl) was stained with phycoerythrin-conjugated (PE) antihemoglobin antibody (anti-Hb) in 0.6% (w/v) NaCl ...

Pistachio is one of the most important horticultural products of Iran with special economic importance. In average 70% of Iran pistachio are exported. Aflatoxin is secondary metabolites of fungus such as Aspergillus flavus and A. parasiticus. If favorite condition is prepared for stabilization of fungi spores producing Aflatoxin, the first pistachio contamination to Aflatoxin occurs in orchard....

The relationship between fungal activity and staining with fluorescein diacetate (FDA) was investigated by growing Penicillium citrinum and Rhizoctonia solani in submerged batch cultures at different initial glucose concentrations and aeration rates. A modified FDA staining method, similar to the Jones and Mollison technique (P. Jones and J. Mollison, J. Gen. Microbiol. 2:54-69, 1948), was deve...

We demonstrate a ligand-specific induction of endocytosis in cells of juvenile brown trout taste buds. The process is fast, massive and selective, as only a few cells in each taste buds are stained by exposure of the oral cavity to the taste stimulant l-cysteine together with a dye at 20 degrees C. Low temperature (+2 degrees C) and disruption of microtubules with nocodazole caused a substantia...

Myelination was studied in aggregating cell cultures derived from mechanically 15- to 16-day fetal rat brains. Myelin basic protein (MBP) and myelin-associated glycoprotein (MAG) were localized immunocytochemically 20-micrometers-thick Vibratome 1-micrometer- thick Epon sections at 15, 20, 25, 30 days vitro. The occurrence of these proteins correlated with the ultrastructural appearance oligode...
