A simple and rapid method is described for the determination of iron in serum by atomic absorption spectrometry with a graphite furnace atomiser. The serum is diluted 40 times with water, and injected into the graphite tube. Optimal conditions are es

Changes in membrane surface properties of hepatic peroxisomes of rats under several conditions were observed by aqueous polymer two-phase systems, which contained 6% (w/w) dextran T 500, 6% (w/w) polyethyleneglycol 4000, 250 mmol sucrose/kg and vario

The binding of gallium 67 or iron 59 to ferritin in vitro was investigated using equilibrium dialysis. Gallium 67 did not bind to apo-ferritin until the protein was transformed into ferritin in the presence of iron citrate. Apotransferrin inhibited t

The in vivo behaviour of Ga-67 citrate was studied, using a rat liver model, and the mechanisms of cellular uptake were investigated by observing the time course of the raidonuclide in subcellular liver cell fractions. Modified continuous ultracentri

Cell surface-associated changes in behaviour of cultured cells on partition in an aqueous two-phase polymer system were studied using FM3A cell line (a cultured mammary cancer of mouse) with respect to aging. The aqueous polymer system consisted of d

In this determination of gallium, the condition of the graphite tubes influences the peak height. Common acids and salts seriously affect the results, but in the presence of EDTA, interferences of nitric and hydrochloric acids are suppressed complete

Gallium adsorption was investigated at various pH values, with and without chelating agents or buffers. Evidence was obtained that Ga-67 citrate was adsorbed to cells in a polymeric form at a certain pH. Adsorption of Ga-67 to cells and to a glass su
