Antibody-antigen complex formation with immobilized immunoglobulins
(Elsevier, 1992-08-15)
We have investigated the complex formation between an immobilized monoclonal antibody and antigens that differ in size about 50-fold. As a model system, we used an iodinated progesterone derivative and a progesterone-horseradish ...
Preparation of polyfunctional diorganomercurials and their transmetallation to diorganozincs. Applications to the preparation of optically active secon
(Elsevier, 1992-10-13)
Two new methods of preparation of functionalized diorganomercurials have been developed. The first method involves a substitution reaction of (ICH2 Their transmetallation with zinc dust (toluene, 80[deg]C, 3-5 h) affords ...
The ecology and evolution of tetracycline resistance
(Elsevier, 1992-09)
The use of tetracycline over the past few decades has been accompanied by a drastic increase in the frequency of tetracycline resistance in a wide range of bacterial species and genera. A diversity of resistance determinants ...
Thermodynamic properties of tungsten ditelluride (WTe2) I. The preparation and lowtemperature heat capacity at temperatures from 6 K to 326 K
(Elsevier, 1992-06)
The heat capacity of the dichalcogenide: tungsten ditelluride, WTe2, was measured over the temperature range 5.5 T/K Cp m occurs in the region 92 T/K Sm = (0.10±0.02) · R. The anomaly coincides with the ...
Formation of a toxic metabolite from gentamicin by a hepatic cytosolic fraction
(Elsevier, 1992-04-15)
We have demonstrated recently that incubation of the aminoglycoside gentamicin with an hepatic post-mitochondrial fraction produces a compound toxic to sensory cells from the inner ear in short-term culture; in contrast, ...
Sites of synthesis of chromogranins A and B in the human brain
(Elsevier, 1992-04)
The sites of synthesis of the chromogranins A and B, and their potential processed peptides, were examined by quantitating the levels of chromogranin A and B mRNA in various regions of the human brain by Northern blot ...
Lipomide dehydrogenase from Azotobacter vinelandii : site-directed mutagenesis of the His450-Glu455 diad
(Blackwell Publishing Ltd, 1992-07)
Assignment of the human CRABP-II gene to chromosome 1q21 by nonisotopic in situ hybridization
(Springer-Verlag, 1992-07)
Two highly conserved forms of cellular retinoic acid binding protein (CRABP-I and CRABP-II) have been described, and one, CRABP-II, is highly expressed in human skin. We have utilized a 10-kb fragment containing the human ...
