Scanning diffractometer for the rapid analysis of microparticles and biological cells
(1979-05-01)
A laser diffractometer is described which employs a novel scanned array of optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180° in approximately ...
Analysis of histones from the yeast Saccharomyces carlsbergensis
(1979-02)
Basic chromosomal proteins were isolated from the chromatin of the yeast Saccharomyces carlsbergensis by extraction with H2SO4 and were purified by ion-exchange chromatography. Electrophoresis of the purified fraction on ...
Detection of a bright ridge in the 2.2 MU-M emission of M82
(1979)
Photometric scans through the central region of M82 with a resolution of 6 arcsec reveal that the 2.2-micron emission source has a compact ridge structure which is approximately aligned + or - 10 deg with the major axis ...
Low-dose electron image reconstruction of negatively stained contractile phage sheath from Bacillus subtilis (PBS-Z)
(1979)
The structure of the contractile sheath of the defective phage from B. subtilis (PBS-Z) has been investigated by low-dose electron microscopy and image reconstruction. The extended and contracted sheath particles were ...
The effect of increased levels of endogenous nerve growth factor on mouse sympathetic ganglia
(1979)
The present experiments showed that treatment of mice with a range of doses of testosterone propionate led to a significant increase in weight of the superior cervical ganglia (SCG). In all cases this was accompanied by ...
High-speed scanning laser diffractometer
(1979)
A high-speed laser diffractometer is described which employs a novel scanned array or optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180 degrees ...
Alterations in the soluble protein patterns of tobacco and cowpea leaves following inoculation with tobacco necrosis virus
(1978-06-01)
Changes in the soluble protein composition of both tobacco and cowpea leaves following inoculation with tobacco necrosis virus (TNV R/1 : 1.5/19 : S/S : S/Fu [1]) have been investigated by the techniques of disc-electrophoresis. ...
Suppression of virus induced local lesions in plasmolysed leaf tissue
(1978-05-01)
It has been demonstrated previously that protoplasts derived from leaves which normally respond in vivo to virus inoculation, with the formation of necrotic local lesions show no such response when inoculated in vitro [1]. ...
