Gentamicin-resistance determinants confer background-dependent hygromycin B resistance
(Mary Ann Liebert, Inc, New Rochelle, 1999)
Micromonospora strains that produce aminoglycoside antibiotics have a high level of resistance to their own products and to structurally similar antibiotics with a 4,6-disubstituted deoxystreptamine aminocyclitol component ...
DNA region responsible for transcriptional regulation of the Escherichia coli penicillin amidase (pac) gene by CRP and PAA
(Elsevier, Amsterdam, 1999)
Transcriptional regulation of Escherichia coli ATCC11105 penicillin amidase gene (pac) by cAMP receptor protein (CRP) and phenylacetic acid (PAA) was studied by using operon fusions with divergent reporter gene (lacZ, and ...
Nuclear extract from REL cells contains GATA-1 transcription factor
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1996)
Preparation of nuclear extracts from different tissues may provide the proteins that regulate gene expression in those tissues. REL (rat erythroleukemia) cells represent a permanent erythroid cell line. They are the most ...
In vitro cultivation of mammalian established cell lines
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1996)
In vitro cell cultures are used in many branches of biology and medicine. The cultivation of mammalian established cell lines is very important, especially as an experimental system indispensable for virusology and gene ...
Ganglioside GM1 and GM3 in early human brain development: An immunocytochemical study
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The distribution of GM1 and GM3 gangliosides in human brain development between gestational week (g.w.) 6 and 15 was demonstrated by an immunocytochemical approach using polyclonal anti-GM1 and anti-GM3 antibodies. The ...
A comparison of the properties of Sox-3 with Sry and two related genes, Sox-1 and Sox-2
(Development, 1996)
The Sox gene family consists of a large number of embryonically expressed genes related via the possession of a 79-amino-acid DNA-binding domain known as the HMG box, Partial clones for the first three Sox genes (a1-a3) ...
Nucleotide sequence of the Escherichia coli K12 histidine operon revisited
(Academic Press, 1994)
We report on a significant difference between the published nucleotide sequence of the Escherichia coli K12 histidine operon and our sequencing results repeatedly obtained from a number of different E. coli K12 strains. ...
The RIB element in the goaG-pspF intergenic region of Escherichia coli
(Amer Soc Microbiology, Washington, 1997)
The sequence (2,700 bp) between the aldH and pspF genes of Escherichia coli was determined, The pspF gene encodes a sigma(54) transcriptional activator of the phage shock protein (psp) operon (pspA to pspE), Downstream of ...
Nucleotide sequence analysis of the inversion termini located within IS3 elements α3β3 and β5α5 of Escherichia coli K-12
(Journal of Bacteriology, 1991)
This paper presents the first detailed structural analysis of termini of an inversion mediated by recombination between Escherichia coli native IS elements. The complete nucleotide sequence of the inversion termini in the ...
