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). ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Transcriptional regulation during T-cell development: the [alpha] TCR gene as a molecular model
(Elsevier, 1992)
The regulation of gene expression during lymphocyte differentiation is a complex process involving interactions between multiple positive and negative transcriptional regulatory elements. In this article, transcriptional ...
Hormonal regulation of steroidogenic enzyme gene expression in Leydig cells
(Elsevier, 1992-12)
In normal mouse Leydig cells, steady state levels of mRNA of CYP11A, 3[beta]-hydroxysteroid dehydrogenase [Delta]5- > [Delta]4-isomerase (3[beta]HSD), and CYP17 are differentially regulated. There is high basal expression ...
Metabolic effects of short-chain ceramide and glucosylceramide on sphingolipids and protein kinase C
(Blackwell Publishing Ltd, 1992-12)
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 ...
Benzimidazole ribonucleosides: Observation of an unexpected nitration when performing non-aqueous diazotizations with t-butyl nitrite
(Elsevier, 1992-09)
Mild, non-acidic conditions used in the non-aqueous diazotization of a 2-aminobenzimidazole nucleoside with t-butyl nitrite gave an unexpected 4-nitrobenzimidazol-2-one nucleoside which was not formed when primary alkyl ...
The effects of menstrual phase and nicotine abstinence on nicotine intake and on biochemical and subjective measures in women smokers: a A preliminary report
(Elsevier, 1992-11)
Nicotine intake, menstrual and smoking withdrawal symptomatology, and baseline cortisol and MHPG were assessed in nine women smokers under conditions of ad lib smoking and overnight abstinence in three menstrual phases ...
New vectors for high level expression of recombinant proteins in bacteria
(Elsevier, 1992-05-01)
A system has been developed for synthesis and rapid purification of recombinant polypeptides expressed in frame with glutathione S-transferase ([3.], Gene 67, 31-40). Expressed fusion proteins are purified from bacterial ...
