Naturally occurring genetic variation affects Drosophila photoreceptor determination
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-02)
The signal transduction pathway controlling determination of the identity of the R7 photoreceptor in the Drosophila eye is shown to harbor high levels of naturally occurring genetic variation. The number of ectopic R7 ...
Comparative gene transfer efficiency of low molecular weight polylysine DNA-condensing peptides
(Munksgaard International PublishersBlackwell Publishing Ltd, 1999-10)
In a previous report (M.S. Wadhwa et al . (1997) Bioconjugate Chem. 8, 81–88), we synthesized a panel of polylysine-containing peptides and determined that a minimal repeating lysine chain of 18 residues followed by a ...
Sequence and developmental expression of amphioxus AmphiNk2–1 : insights into the evolutionary origin of the vertebrate thyroid gland and forebrain
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-03)
We characterized an amphioxus NK-2 homeobox gene ( AmphiNk2–1 ), a homologue of vertebrate Nkx2–1 , which is involved in the development of the central nervous system and thyroid gland. At the early neurula stage of ...
Elderberry bark lectin-gold techniques for the detection of Neu5Ac (α2,6) Gal/GalNAc sequences: applications and limitations
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-09)
The lectin from the elderberry ( Sambucus nigra L.) bark, shown to recognize the sequence neuraminic acid (α2,6) galactose/ N -acetylgalactosamine, was applied for detecting binding sites in Lowicryl K4M sections by light ...
Relationship among fibre type, myosin ATPase activity and contractile properties
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1982-11)
At least two types of skeletal muscle myosin have been described which differ in ATPase activity and stability in alkaline or acidic media. Differences in ATPase characteristics distinguish Type I and Type II fibres ...
