Comparison of methods of analysis of polychlorinated biphenyls in oils
(Elsevier, 1983)
In order to standardize and validate methods for the analysis of polychlorinated biphenyls in transformer oil, waste oil, hydraulic fluid and capacitor oil in the concentration range 30-500 ppm, a study was performed which ...
Dynorphin reduces voltage-dependent calcium conductance of mouse dorsal root ganglion neurons
(Elsevier, 1984-12)
Dynorphin A (DYN) (1 [mu]M) decreased somatic calcium-dependent action potential (CAP) duration of a portion of dorsal root ganglion (DRG) neurons in a naloxone reversible manner. Responses to DYN differed from responses ...
A solid support for affinity chromatography that covalently binds thiol groups via a cleavable connector arm
(Elsevier, 1980-09)
Preparation of an agarose derivative (MPE-agarose) containing a maleimido group which is attached to agarose via a cleavable phenyl ester linkage is described. MPE-agarose was shown to react with the thiol groups in ...
[beta]-Glucosidase activator protein from bovine spleen ("coglucosidase")
(Elsevier, 1981-04-15)
[beta]-Glucosidase-stimulating proteins ("co-[beta]-glucosidase") have been isolated from bovine spleen by acidification of homogenized spleen, heat denaturation, and chromatography with DEAE-Sephacel, Sephadex G-75, ...
New spectrophotometric and radiochemical assays for acetyl-CoA: Arylamine N-acetyltransferase applicable to a variety of arylamines
(Elsevier, 1985-03)
Simple and sensitive spectrophotometric and radiochemical procedures are described for the assay of acetyl-CoA:arylamine N-acetyltransferase (NAT; EC 2.3.1.5), which catalyzes the reaction acetyl-CoA + arylamine --> ...
Relationship of thromboxane generation to the aggregation of platelets from humans: Effects of eicosapentaenoic acid
(Elsevier, 1985-11)
A non-linear relationship between the percent aggregation of human platelets and the amount of TXB2 generated requires investigators to use caution when using the data to assess antiplatelet regimens. The relationship ...
Murine glucocorticoid receptors and the H-2 locus--A reappraisal
(Elsevier, 1984-12)
It has been demonstrated that susceptibility to glucocorticoid-induced formation of cleft palate is regulated by the mouse histocompatibility complex (H-2). This has encouraged us to examine H-2 effects on glucocorticoid ...
Quantitation of lipids by charring on thin-layer plates and scintillation quenching: Application to ceramide determination
(Elsevier, 1981-04)
A method is described for the quantitative determination of lipids after separation by thin-layer chromatography: the lipid spots are visualized with a charring spray and the darkness of the spots is determined by measuring ...
Mechanisms of gentamicin-induced dysfunction of renal cortical mitochondria : II. Effects on mitochondrial monovalent cation transport
(Elsevier, 1980-11)
Mitochondrial swelling techniques were used to evaluate the effects of the aminoglycoside antibiotic gentamicin on renal cortical mitochondrial monovalent cation permeability. Gentamicin behaved like EDTA to enhance ...
