A rapid and sensitive screening method for the detection of anti-2-acetylaminofluorene immunoglobulins
(Elsevier, 1988-04-22)
A method is described in which anti-2-acetylaminofluorene immunoglobulins may be detected using a simple and sensitive screening procedure. The method is based on immunoglobulin binding of an 125I derivatized 2-aminofluorene ...
Dynamics of energy transport in ternary molecular solids. I. Naphthalene steady state fluorescence
(Elsevier, 1981-05-01)
Energy transport experiments were conducted at liquid helium temperatures on ternary single crystals (host/guest/ supertrap, i.e. C10H8/C10D8/betamethylnaphthalene-d10) at guest concentrations of 50--99% and very low (about ...
The illumination of molecular behavior by electron waves
(Elsevier, 1985-01)
Aspects of vapor-phase electron diffraction are discussed, singling out the seminal contributions of Yonezo Morino in collaboration with San-ichiro Mizushima and others. Recent developments leading to a precision approaching ...
Measurement of ammonia and glutamine in cell culture media by gas sensing electrodes
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-04)
This paper describes the use of a commercially available off-line gas sensing electrode for determination of ammonia and glutamine in cell culture media. The measurement technique was tested in different media preparations ...
Two-particle continuous-time random walks and binary reactions in disordered media
(Elsevier, 1984-02-10)
The relation between unary-(trappihg) and binary (mutual annihilation) reactions in disordered systems is studied in the framework of the continuous-time random walk. It is found that if the waiting-time distribution of ...
The mechanism of amine inhibition of the photosynthetic oxygen evolving complex : Amines displace functional chloride from a ligand site on manganese
(Elsevier, 1983-10-17)
Amines inhibit photosynthetic oxygen evolution by binding to manganese in the oxygen evolving complex. This inhibition is more effective if chloride is absent. Steady-state kinetic analyses show that ammonia and chloride ...
Monovalent cations (Na+, K+, Cs+) inhibit calcium activation of photosynthetic oxygen evolution
(Elsevier, 1989-02-13)
In the absence of the 17 and 23 kDa water-soluble polypeptides, the oxygen-evolving complex of photosystem II requires addition of Cl- and Ca2+ to maximize rates of oxygen evolution activity. We have found that monovalent ...
Pseudopotential SCF–MO studies of hypervalent compounds. I. XeF2 and XeF4
(The American Institute of Physics, 1980-07-01)
The (ab initio) effective potential theory developed by Ewig et al. has been applied to a series of hypervalent compounds with a view to elucidating the anomalous properties of several of the higher fluorides of xenon and ...
An investigation of Prussian Blue analogues by Mossbauer spectroscopy and magnetic susceptibility
(Elsevier, 1984)
The Mossbauer spectra and magnetic susceptibilities have been obtained for a series of Prussian Blue analogues of general formula MjA[MB(CN)6]k[middle dot]mH2O where MA and MB are transition metal ions, j and k vary with ...
