Assessment of metrezoate-labeled gallium transmission in cultured human Burkitt lymphatic cells

Background: In addition to determining the exact tumor location and its geometric features, an increase of the effective tumor atomic number will enhances the chance in treating the tumoral cells under suitable radiation. In the present study, we assessed metrezoate-labeled gallium transmission in Burkett lymphatic cells. Materials and Methods: Human Burkitt lymphatic cells were grown ...

Myofibrillogenesis in living cells microinjected with fluorescently labeled alpha-actinin

Fluorescently labeled alpha-actinin, isolated from chicken gizzards, breast muscle, or calf brains, was microinjected into cultured embryonic myotubes and cardiac myocytes where it was incorporated into the Z-bands of myofibrils. The localization in injected, living cells was confirmed by reacting permeabilized myotubes and cardiac myocytes with fluorescent alpha-actinin. Both living and permea...

Metabolism and intracellular localization of a fluorescently labeled intermediate in lipid biosynthesis within cultured fibroblasts

In this paper we report on the uptake and distribution of an exogenously supplied fluorescent phosphatidic acid analogue by Chinese hamster fibroblasts. Under appropriate in vitro incubation conditions, 1-acyl-2-(N-4-nitrobenzo-2-oxa-1,3-diazole)-aminocaproyl phosphatidic acid was rapidly and preferentially transferred from phospholipid vesicles to cells at 2 degrees C. However, unlike similar ...

Molecular cytochemistry: incorporation of fluorescently labeled actin into living cells.

Actin labeled with 5-iodoacetamidofluorescein has been incorporated into the functional pool of actin in Chaos carolinensis and Physarum polycephalum by direct microinjection. The functional activity of the labeled actin has been analyzed at three levels of organization as: (a) with the purified actin, (b) in motile extracts of cells, and (c) in living motile cells. The labeled actin exhibited ...

Anisotropic diffusion of fluorescently labeled ATP in rat cardiomyocytes determined by raster image correlation spectroscopy

A series of experimental data points to the existence of profound diffusion restrictions of ADP/ATP in rat cardiomyocytes. This assumption is required to explain the measurements of kinetics of respiration, sarcoplasmic reticulum loading with calcium, and kinetics of ATP-sensitive potassium channels. To be able to analyze and estimate the role of intracellular diffusion restrictions on bioenerg...
