Dantrolene Sodium

The binding of dantrolene to rabbit red blood cell (RBC) ghosts and bovine serum albumin as models of receptor sites was studied using fluorescence techniques. Dantrolene upon binding to rabbit RBC ghosts and bovine serum albumin showed fluorescence with emission maxima at 495 and 500 nm, respectively. Dantrolene bound to rabbit RBC ghosts with an association constant of 6.06 × 104 M−1 and there were 2.4 × 106 dantrolene binding sites per ghost. The binding of dantrolene to bovine serum albumin showed an anomaly with respect to dantrolene concentration. Dantrolene at concentrations of 1.25 – 3.75 μM bound to bovine serum albumin with an association constant of 1.72 × 104 M−1 and there were 1.078 binding sites/mol bovine serum albumin. The higher affinity of dantrolene toward blood cells was confirmed by studying the distribution of dantrolene between blood cells and plasma after a single i.p. injection of dantrolene sodium (3 mg/kg) to albino rabbits. It was found that the concentration of dantrolene in rabbit blood cells was 2.76 times that of plasma.

As If

We recently described an artificial substrate system which could be used to optimize labeling parameters in EM immunocytochemistry (ICC). The system utilizes blocks of glutaraldehyde polymerized bovine serum albumin (BSA) into which an antigen is incorporated by a soaking procedure. The resulting antigen impregnated blocks can then be fixed and embedded as if they are pieces of tissue and the effects of fixation, embedding and other parameters on the ability of incorporated antigen to be immunocyto-chemically labeled can then be assessed. In developing this system further, we discovered that the BSA substrate can also be dried and then sectioned for immunolabeling with or without prior chemical fixation and without exposing the antigen to embedding reagents. The effects of fixation and embedding protocols can thus be evaluated separately.

SummaryThe biological half-life of prostacyclin in Krebs solution, human cell-free plasma or whole blood was measured by bracket assay on ADP-induced platelet aggregation. At 37°C, pH 7.4, plasma and blood reduced the rate of loss of antiaggregatory activity compared with Krebs solution. The protective effect of plasma was greater than that of whole blood. This effect could be partially mimicked by the addition of human or bovine serum albumin to the Krebs solution. The stabilisation afforded by human serum albumin was dependent on the fatty acid content of the albumin, although this was less important for bovine serum albumin.

ABSTRACT A radioimmunoassay was developed to measure the levels of oestrone and oestradiol in 0.5–1.0 ml of domestic fowl peripheral plasma. The oestrogens were extracted with diethyl ether, chromatographed on columns of Sephadex LH-20 and assayed with an antiserum prepared against oestradiol-17β-succinyl-bovine serum albumin using a 17 h incubation at 4°C. The specificity, sensitivity, precision and accuracy of the assays were satisfactory. Oestrogen concentrations were determined in the plasma of birds in various reproductive states. In laying hens the ranges of oestrone and oestradiol were 12–190 pg/ml and 29–327 pg/ml respectively. Levels in immature birds, in adult cockerels and in an ovariectomized hen were barely detectable. The mean concentrations of oestrone and oestradiol in the plasma of four non-laying hens (55 pg/ml and 72 pg/ml respectively) and one partially ovariectomized hen (71 pg/ml and 134 pg/ml respectively) were well within the range for laying hens. It is evident that the large, yolk-filled follicles are not the only source of oestrogens in the chicken ovary.
