Effect of anchorage dependency on growth rate and monoclonal antibody production of hybridoma cells
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-05)
Hybridoma cells (S3H5/γ2bA2) are found to grow either in suspension or as attached to the surface of cell culture T flask. Cell growth rates and monoclonal antibody (MAB) production rates of both suspended and attached ...
Ethanolaminephosphotransferase in rat lung: selectivity for endogenous and exogenous diacylglycerol
(Elsevier, 1988-05-02)
Ethanolaminephosphotransferase (EC 2.7.8.1) activity was determined in lung microsomes using diacylglycerols generated endogenously from [14C]glycerol 3-phosphate and different mixtures of fatty acids Ethanolaminephospho ...
Homogeneous enzyme-linked competitive binding assay for riboflavin
(Elsevier, 1988)
A rapid and precise homogeneous enzyme-linked competitive binding assay for riboflavin (vitamin B2) is described. The method utilizes a malate dehydrogenase/3-carboxymethylriboflavin conjugate in conjunction with soluble ...
Structural characterization of the sulfur-capped triangulo cluster, Cp2W2Fe(CO)7(S)
(Elsevier, 1988-09-06)
Cp2W2(CO)4(W[triple bond]) reacts with Fe2(CO)6([mu]-S2) to give Cp2W2Fe(CO)7([mu]3-S) (1) (10%) and Cp2W2Fe2(CO)8([mu]3-S)2 (5%). Spectral properties, cyclic voltammetry, and the structure of 1 are reported. Cluster 1 is ...
Stabilization mechanism of colloidal suspensions by gum tragacanth: The influence of pH on stability
(Elsevier, 1988-11)
An acidic polyelectrolyte, gum tragacanth (GT), was found to stabilize polystyrene latex particles due to a steric stabilization mechanism. The stability depends significantly on the pH of the solution. To elucidate the ...
Domain Switching as a Toughening Mechanism in Tetragonal Zirconia
(Blackwell Publishing Ltd, 1988-07)
Dipole derivatives and infrared intensities of the ester group. An ab initio and force field study of methyl acetate
(Elsevier, 1988-10-31)
Dipole derivatives have been obtained (using both 3-21G and 6-31G basis sets) for methyl acetate. Using a force field refined from experimental data on methyl acetate and its deuterated derivatives, infrared intensities ...
Thermodynamics of uranium intermetallic compounds II. Heat capacity of UPd3 from 8 to 850 K
(Elsevier, 1988-07)
The heat capacity (from 8 to 350 K) of UPd3 by adiabatic calorimetry and (from 400 to 900 K) by enthalpy-increment drop calorimetry has been measured and the thermodynamic properties at 298.15 K have been evaluated as ...
Fractographic study of transverse cracks in a fibre composite
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-07)
Transverse fracture of unidirectional fibre composites was studied in a model glass/epoxy composite in which 1 mm-diameter rods had been used in place of fibres. The fracture surface resulting from transverse cracking in ...
Plane-stress crack-tip fields for power-law hardening orthotropic materials
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-07)
Plane stress mode I near-tip fields in orthotropic materials are examined. Plastic orthotropy is described by Hill's quadratic yield function and the strain hardening behavior is given by an appropriate generalization of ...
