Localization of a human T-cell-specific gene, RANTES (D17S136E), to chromosome 17q11.2-q12
(Elsevier, 1990-03)
We report here the localization of the gene for a human T-cell-specific molecule, designated RANTES, to human chromosome region 17q11.2-q12 by in situ hybridization and analysis of somatic cell hybrids using a cDNA probe ...
Positive-ion thermospray liquid chromatography--mass spectrometry: detection of organic acidurias
(Elsevier, 1990)
Positive-ion thermospray liquid chromatography--mass spectrometry (TSP-LC-MS) is used to detect organic acids via the direct injection of untreated urine from newborns and infants. Two methods are reported for the separation ...
Heat capacity of deuterated ammonium tetrafluoroborate ND4BF4 from 7 K to 348 K
(Elsevier, 1990-10)
The heat capacity of deuterated ammonium tetrafluoroborate ND4BF4 was measured from 7 K to 348 K by adiabatic calorimetry. The curve for heat capacity against temperature is smooth with a broad maximum between 120 K and ...
Structure and chromosomal localization of the human thrombospondin gene
(Elsevier, 1990-04)
Thrombospondin (THBS1) is a large modular glycoprotein component of the extracellular matrix and contains a variety of distinct domains, including three repeating subunits (types I, II, and III) that share homology to an ...
Prenatal diagnosis and linkage disequilibrium with cystic fibrosis for markers surrounding D7S8
(Springer-Verlag, 1990-08)
Three polymorphic DNA markers surrounding the D7S8 locus were tested for their usefulness in the diagnosis of cystic fibrosis (CF) by linkage analysis. The markers correspond to the loci D7S424 and D7S426. These polymorphisms ...
Ion-pair chromatography of inositol polyphosphates with N-methylimipramine
(Elsevier, 1990)
A novel counter-ion, N-methylimipramine, was synthesized and utilized in the separation of inositol phosphates by ion-pair chromatography. The structural identity of the counter-ion was documented by nuclear magnetic ...
Role of the CD28 receptor in T-cell activation
(Elsevier, 1990)
Antigen-specific T-cell activation is initiated through the T-cell receptor. Recent evidence has shown that a number of additional T-cell surface receptors serve to regulate the responses of antigen-activated T cells. One ...
Preparation of functionalized zinc and copper organometallics containing sulfur functionalities at the alpha or gamma position
(Elsevier, 1990)
[alpha]-Chloroalkyl phenyl sulfides 1 readily insert zinc in THF at 25 [deg]C (0.5-2 h), affording sulfur stabilized organozinc derivatives of type 2. The presence of a functional group such as an ester or a cyano group ...
Thermodynamic properties of ammonium haloplatinates I. Heat capacity and thermodynamic functions of ammonium hexachloroplatinate (NH4)2PtCl6 from 6 K to 348 K
(Elsevier, 1990-11)
The heat capacity of ammonium hexachloroplatinate (NH4)2PtCl6 was measured from 6 K to 348 K by adiabatic calorimetry. The heat-capacity curve is sigmate without anomalies. It rises rapidly from T --> 0 to 250 K where ...
