Simultaneous separation and purification of neurofilament and glial filament proteins from brain.


Neurofilaments (NF) and glial filaments (GF) were purified from bovine brain by the axonal flotation method, followed by hydroxylapatite chromatography in 8 M-urea. The proteins were shown to be competent to reassemble into intermediate filaments with removal of the denaturant, and reassembly was used as the final step in the purification of the filament… (More)
