Heteroplasmy of chloroplast DNA in Medicago
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-01)
Two chloroplast DNA (cpDNA) regions exhibiting a high frequency of intra- or inter-species variation were identified in 12 accessions of the genus Medicago . Restriction maps of both regions were prepared for alfalfa, and ...
Properties of the genome in normal and SV-40 transformed WI-38 human diploid fibroblasts. III. Turnover of nonhistone chromosomal proteins and their phosphate groups
(Elsevier, 1975-04-01)
The turnover of nonhistone chromosomal proteins and their phosphate groups was compared in normal and in SV-40 virus transformed WI-38 human diploid fibroblasts. Cells were pulse labelled with tryptophan-3H and 32P for 30 ...
Cross-species conservation of a polymorphic dinucleotide repeat in the dystrophin gene
(Springer-Verlag, 1992-05)
Location of the 9257 and ataxia mutations on mouse Chromosome 18
(Springer-Verlag; Springer-Verlag New York Inc., 1996-06)
The location of three mutations on proximal Chromosome (Chr) 18 was determined by analysis of the offspring of several backcrosses. The results demonstrate that ataxia and the insertional mutation TgN9257Mm are separated ...
Macromolecular organization and genetic mapping of a rapidly evolving chromosome-specific tandem repeat family (B77) in cotton (Gossypium)
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-12)
Isolation and characterization of the most prominent repetitive element families in the genome of tetraploid cotton (Gossypium barbadense L; [39]) revealed a small subset of families that showed very different properties ...
Properties of the tryptophan residue in rabbit liver microsomal cytochrome P-450 isozyme 2 as determined by fluorescence
(Elsevier, 1985-04-30)
Cytochrome P-450 isozyme 2 from rabbit liver microsomes fluoresces upon excitation at 295 nm due to the single tryptophyl residue (Trp121) in the protein. The fluorescence spectrum, which is not altered by the presence of ...
Immunological relatedness of two isozymes of 3-phosphoglycerate kinase from the mouse
(Elsevier, 1978-11-15)
Protein kinase C and clostridial neurotoxins affect discrete and related steps in the secretory pathway
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-12)
1. The effects on catecholamine secretion of activation of protein kinase C and clostridial neurotoxins were examined in digitonin-permeabilized bovine adrenal chromaffin cells.
Resolution in the receptor binding of putative [mu] and [kappa] opiates
(Elsevier, 1984-05-28)
Conditions for the stereospecific binding of 3H-ethylketocyclazocine and 3H-etorphine were established in membranes from rat and pigeon brain. In displacing the specific binding of the radiolabeled ligands, putative [mu] ...
Selection of rare event cells expressing [beta]-galactosidase
(Elsevier, 1991-06)
The ACAS Interactive Laser Cytometer was used to screen and select mammalian cells in culture infected with a retrovirus construct containing the Escherichia coli lacZ and neomycin resistance genes. The product of expression ...
