Purification of an anticoagulant from the body fluid of Ascaris suum.
An anticoagulant has been purified from the body fluid of Ascaris suum by sequential passage through Sephadex G-50, CM-cellulose and Sephadex G-25 columns then treated with 2 M NaCl, passaged through a Sephadex G-25 column, separated from the phosphate buffer by precipitation of the latter with the CaCl2, then passaged through a Sephadex G-10 column in water. In the body fluid of the worm, the anticoagulant is ionically-bound to a carrier substance. The complex can be split by treatment with 2 M NaCl. The molecular weight of the anticoagulant is slightly less than 1400.
