A polarographic method for following the rates of cholinesterase-catalyzed hydrolyses of acetylthiocholine
(Elsevier, 1965-08)
A rapid and simple polarographic method for following the rates of the cholinesterase-catalyzed hydrolysis of acetylthiocholine and the rates of inhibition of this hydrolysis is described. This method has the advantage ...
cDNA and derived amino acid sequence of rabbit nasal cytochrome P450NMb (P450IIG1), a unique isozyme possibly involved in olfaction
(Elsevier, 1991-02-15)
Olfactory-specific cytochrome P450NMb was previously purified to electrophoretic homogeneity from microsomes of rabbit nasal mucosa in this laboratory. In the present study, a cDNA library made from poly(A)+ RNA from rabbit ...
Actin polymerization in cellular oxidant injury
(Elsevier, 1991-08-01)
Microfilaments undergo an ATP-dependent disruption into shortened bundles following cellular exposure to oxidants. This phenomenon does not require a net change in the amount of polymerized actin. However, increased amounts ...
Gas chromatographic separtion of low molecular weight fluorocarbons
(Elsevier, 1968)
Application of gas-solid chromatography techiques to the separation of low molecular weight fluorocarbons incorporates a number of advantages over previous analysis techniques. These advantages include isothermal operation ...
Conversion of dehydroepiandrosterone sulfate to androst-5-enediol-3-sulfate by soluble extracts of rat testis
(Elsevier, 1965-09)
3H-Androst-5-ene-17-one-3[beta]-y1 sulfate is converted to 3H-androst-5-ene-17[beta]-o1-3[beta]-y1 sulfate by soluble extracts of rat testis in the presence of added NADH2 or NADPH2.The conversion was approximately 4 times ...
Hormonal regulation of steroidogenic enzyme gene expression in Leydig cells
(Elsevier, 1992-12)
In normal mouse Leydig cells, steady state levels of mRNA of CYP11A, 3[beta]-hydroxysteroid dehydrogenase [Delta]5- > [Delta]4-isomerase (3[beta]HSD), and CYP17 are differentially regulated. There is high basal expression ...
Immunochemical studies on the binding specificity of the blood group Leb specific lectin Griffonia simplicifolia IV
(Elsevier, 1983-05)
The specificity of the Griffonia simplicifolia IV (GS-IV) lectin was studied by quantitative precipitin and quantitative precipitin inhibition assays. The lectin precipitated most strongly with a human H,Leb blood group ...
