摘要:

The specific antibodies anti-influenza virus A2/Aichi/68 were combined immunologically with the virus purified by zonal centrifugation, then dissociated by lowering the pH and conjugated with horseradish peroxidase using glutaraldehyde as the coupling agent. With so labeled antibodies it was possible to detect the viral antigen in infected chick embryo kidney cells with the light microscope. This work suggests that the immunoperoxidase technique could be useful for early rhinocytologic diagnosis of influenza virus infections.

摘要:

An examination of the fine structure ofAnacystis nidulans, a blue-green alga, has revealed an association between the electron-dense polyphosphate granules and the cyanophycin granules sometimes referred to as lamellasomes. It is possible that the deposition of phosphate occurred within the cyanophycin granule.

摘要:

A chemically defined medium was formulated for the vegetative growth ofBacillus sphaericusNCA Hoop 1-A-2. Growth was enhanced by supplementing with synthetic or naturally occurring chelators. In the presence of EDTA, in addition to increased growth, the strain sporulated to varying degrees.
