Immobilized glucose oxidase and -amino acid oxidase: A convenient method for the purification of flavin adenine dinucleotide and its analogs
(Elsevier, 1979-05)
The preparation of flavin adenine dinucleotide-affinity columns employing glucose oxidase and -amino acid oxidase covalently linked to Sepharose-4B is described. Both immobilized enzymes have very good long-term stabilities, ...
Synthesis of p-nitrophenyl 2-O-[alpha]--mannopyranosyl-[alpha]--mannopyranoside and p-nitrophenyl 6-O-[alpha]--mannopyranosyl-[alpha]--mannopyranoside
(Elsevier, 1979-12)
Crystalline 2-O-[alpha]--mannopyranosyl-[beta]--mannopyranose octaacetate was synthesized by condensation of tetra-O-acetyl-[alpha]--mannopyranosyl bromide (3) with 1,3,4,6-tetra-O-acetyl-[beta]--mannopyranose. ...
Calculation of adsorption-related parameters from a.c. polarographic data: : Basis and Computer Programs
(Elsevier, 1979-12-03)
Phase-selective alternating current polarography can be advantageously used for the observation and quantitative description of adsorption at a solution--electrode interface; for example, in the absence of a faradaic ...
Properties of NADPH-cytochrome P-450 reductase purified from rabbit liver microsomes
(Elsevier, 1979-07)
NADPH-cytochrome P-450 reductase has been purified to electrophoretic homogeneity from rabbit liver microsomes by a procedure that may be used in conjunction with the isolation of the major forms of cytochrome P-450. The ...
Schrodinger equation for a dirac bubble potential
(Elsevier, 1979-07-15)
The quantum-mechanical problem of a particle moving in a "Dirac bubble potential" U(r) = ([lambda]/ro)[delta](r - ro) is solved exactly for both bound and continuum states by making use of partial wave Green's functions ...
The preparations and decompositions of some chloroacetyl-transition metal derivatives
(Elsevier, 1979-06-12)
The reactions of ClCH2COCl with NaM(CO)3C5H5 (M = Cr, Mo, W), NaM'(CO)5 M' = Mn, Re), NaFe(CO)2C5H5, (Ph3P)4Pt and Cl(CO)(Ph3P)2Ir were examined. The chloroacetylmetal derivatives, C5H5(CO)3MCOCH2Cl (M = Mo, W), ...
Energy transfer in one-, two-, and three-dimensionally coupled salts of divalent manganese
(Elsevier, 1979-12-01)
The emission spectra of several antiferromagnetic complexes of divalent manganese (CsMnBr3, Rb2MnCl4, CsMnCl3 and KMnCl3) which contain rare-earth ion impurities have been studied as a function of temperature. In all cases ...
Composition of proteoglycans in cartilages of gunn rats
(Elsevier, 1979-08-06)
The ability of homozygous Gunn rats to conjugate trimethylacetic acid with glucuronic acid was significantly reduced from that of the heterozygous Gunn rats. This was interpreted as indicative of a reduced glucuronosyl ...
Current concepts of morphology of amorphous polymers-- II. Degree of local order and overall chain conformation
(Elsevier, 1979)
After a brief discussion on our earlier electron microscopyrresults of amorphous polymers and the results obtained by others in recent years from small angle neutron scattering and optical anisotropy measurements, it is ...
A direct synthesis of substituted thiophenes [alpha]-oxoketene dithioacetals. II.
(Elsevier, 1979)
The regioselective deprotonation of S,S-dimethyl-[alpha]-oxoketene dithioacetal at the (Z)-S-methyl group leads to a direct synthesis of 2-S-methyl-3,4-disubstituted thiophenes.
