Abstract. To determine the effect of steroid occupancy of the glucocorticoid receptor on the measurement of total receptor concentration using Scatchard plot of [3H]dexamethasone (Dex) binding to circulating leukocytes, leukocytes were incubated with 10−7m cortisol or 10−9m Dex prior to [3H]Dex binding study. Total binding capacity calculated from Scatchard plot analysis of [3H]Dex binding was not significantly reduced after pre-incubation with cortisol. However, total binding capacity was significantly lower after pre-incubation with Dex. These data suggest that total glucocorticoid receptor concentration can be measured from a 3 h incubation of leukocytes obtained from untreated patients.

The binding of 14C-labelled bovine and porcine malate dehydrogenase (EC 1.1.1.37) to rat liver mitochondria and mitoplasts was examined. The bovine enzyme was found to associate nonspecifically with isolated mitochondria and sonicated mitoplasts. Scatchard plot analysis suggested a specific binding to mitoplasts of the order of 5 pmol malate dehydrogenase per milligram of mitoplast protein. Porcine malate dehydrogenase dimer but not monomer exhibited a similar binding. The results are discussed in relation to the mechanism of uptake of the enzyme by mitochondria after synthesis on cytosolic ribosomes.

Cytosolic oestrogen receptors (ER(c)) were determined with a Dextran-coated charcoal assay and Scatchard plot analysis in endometrial tissue of non-pregnant and pregnant gilts on Days 10-13 after standing oestrus. The Kd of the ER(c) was 0.40 +/- 0.04 nM (mean +/- SEM) and was not affected by day or reproductive state. The endometrial ER(c) concentration was affected by day and reproductive state (P

AbstractThe pH dependence of the stability constant of Np(V)-humate and the sorption of Np(V) onto soil was studied to clarify the influence of dissolved organic carbon on the migration behavior of Np(V) in soil layer. The stability constant of Np(V)-humate was expressed by logβ1=(0.35 ±0.03)pH+0.04±0.01 in the pH region from 5.3 to 8.7, and the intrinsic stability constant by logβ*1=3.66±0.05.The sorption of Np(V) increased with pH up to pH 7, and tended to reach maximum, about 95%, at pH 9 in the absence of humic acid. In the presence of humic acid more than 140mg/l, the sorption of Np(V) was lower than that in the absence of humic acid above pH 7, while any influence of humic acid on the sorption of Np(V) onto soil was not observed below pH 7. The sorption behavior of Np(V) onto soil was explained by reversible sorption of NpO2+ and sorption of NpO2CO3- and/or NpO2OH. Further, the influence of the size distribution of Np(V) on the sorption onto soil was examined and discussed.
