THE PRECIPITIN REACTION OF THYROGLOBULIN

摘要: Thyroglobulin, first isolated by Oswald, is a comparatively constant compound in different species, except, of course, for variations the iodin content. So far as we can learn, antigenic properties thyroglobulin have not been studied, and it occurred to us that would be interest study them. Accordingly, prepared from beef, swine, human thyroids usual way, but with special efforts obtain pure product possible. The were freed fat connective tissue torn into small pieces, which washed water until almost white, then extracted icebox salt solution containing little thymol. After being filtered through paper several times, extract was precipitated an equal quantity concentrated ammonium sulphate solution, precipitate 50 per cent. dissolved
