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 ...
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 ...
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 ...
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 ...
