A radiation hybrid map of the proximal short arm of the human X chromosome spanning incontinentia pigmenti 1 (IP1) translocation breakpoints
(Elsevier, 1992-11)
Radiation hybrid mapping was used in combination with physical mapping techniques to order and estimate distances between 14 loci in the proximal region of the short arm of the human X chromosome. A panel of radiation ...
Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Effect of Neuropeptide Y on Natural Killer Activity of Normal Human Lymphocytes
(Elsevier, 1993-03)
The in vitro effect of neuropeptide Y (NPY) on natural killer (NK) cell activities of normal lymphocytes was investigated. NPY at 10-9 to 10-12M concentrations produced significant suppression of NK activity against K 562 ...
Protein tyrosine phosphatases: characterization of extracellular and intracellular domains
(Elsevier, 1994-02)
Protein tyrosine phosphatases (PTPs) play an important role in the regulation of cell growth and differentiation. With over 30 PTPs identified, the specific functions of these enzymes are now being addressed. The identification ...
The cloned butyrylcholinesterase (BCHE) gene maps to a single chromosome site, 3q26
(Elsevier, 1991-10)
Human tissues have two distinct cholinesterase activities: acetylcholinesterase and butyrylcholinesterase. Acetylcholinesterase functions in the transmission of nerve impulses, whereas the physiological function of ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
Synthesis of normal and variant human hypoxanthine-guanine phosphoribosyltransferase in Escherichia coli
(Elsevier, 1993-01-30)
Naturally occurring mutations in hypoxanthine-guanine phosphoribosyltransferase (HPRT) have been identified by amino acid sequencing, cDNA cloning, and direct nucleotide sequencing of PCR-amplified transcripts. To determine ...
Nucleotide Sequence Analysis of 77.7 kb of the Human V[beta] T-Cell Receptor Gene Locus: Direct Primer-Walking Using Cosmid Template DNAs
(Elsevier, 1994-03-15)
The nucleotide sequence of 77.7 kb from the human T-cell receptor [beta]-chain locus was determined directly from three overlapping cosmid clones using the primer-walking approach. Computer-aided analyses of this sequence ...
Kinetics of aerobic biodegradation of benzene and toluene in sandy aquifer material
(Kluwer Academic Publishers; Springer Science+Business Media, 1991-03)
Monod's equation adequately described aerobic biodegradation rates of benzene and toluene by the microbial population of a sandy aquifer when these compounds were initially present at concentrations lower than 100 mg/l ...
NF1-related locus on chromosome 15
(Elsevier, 1992-08)
A neurofibromatosis type I (NF1)-related locus has been identified on chromosome 15. It contains a partial copy of the NF1 GAP-related domain, which is known to interact with the ras protooncogenes. However, the chromosome ...
