A Direct Scanning Apparatus for Reading Electrophoretic Paper Strips
Louis L. Griffiths · Journal of Clinical Pathology · 1952
Since the publication of papers on the electro-phoresis of serum proteins in filter paper strips by Cremer and Tiselius (1950), Durrum (1950), Turba and Enenkel (1950), and Flynn and de Mayo (1951), several attempts have been made to simplify the technique by the elimination of the tedious elution and subsequent estimation of the protein fractions. Grassmann, Hannig, and Knedel (1951) rendered the strip translucent with anisol ana it was then read in the special apparatus described by Knedel (1951). This is unobtainable in Britain and the method of construction results in a graph of small dimensions which is difficult to analyse. A much simpler apparatus was devised, which, while accurate, had the disadvantage that it was not permanent, but
