BACKGROUND Nuclear objects that have in common the property of being recognized by monoclonal antibodies specific for phosphoprotein epitopes and cytoplasmic intermediate filaments (in particular, SMI-31 and RT-97) have been reported in glial and neuronal cells, in situ and in vitro. Since neurofilament and glial filaments are generally considered to be(More)
Melatonin is an important hormone regulating circadian clocks in birds, but the specific cellular sites of action are not completely known. The present study was designed to determine whether astrocytes derived from chick brain contained functional melatonin receptors. Primary cell cultures of diencephalon astrocytes that express glial fibrillary acidic(More)
One of the key elements in point-of-care (POC) diagnostic test instrumentation is the optical system required for signal detection and/or imaging. Many tests which use fluorescence, absorbance, or colorimetric optical signals are under development for management of infectious diseases in resource limited settings, where the overall size and cost of the(More)
Monoclonal antibody J1-31 was raised against plaque materials taken from brains of patients who had suffered from multiple sclerosis (MS). Preliminary characterization of the antigen revealed it to be a protein of M(w) 68-70 kDa with both a cytoplasmic and nuclear localization. Here we report the results of isolation and peptide sequencing of the antigen(More)
