X-RAY DIFFRACTION	?	?	CRYSTALLIZED IN 50 MM TRIS-HC1 2.4 M AMMONIUM SULFATE PH 8. 5 AND 1 MM HGC12 AT 4 DEG C (TILANDER, B., STRANDBERG, B. & FRIDBORG, K. (1965). CRYSTAL STRUCTURE ON HUMAN ERYTHROCYTIC CARBONIC ANHYDRASE C. J. MOL. BIOL. 12, 740-760). THE MERCURY IS SUBSEQUENTLY REMOVED BY MERCAPTOETHANOL AND THE ZINC ION WITH DIPICOLINATE. AFTER INSERTION OF COBALT (II), THE CRYSTALS ARE SOAKED IN 0.25 M BICARBONATE 3M AMMONIUM SULFATE 50 MM TRIS-HC1 PH 8.1 OVERNIGHT. THE PROCEDURE IS DESCRIBED IN DETAIL IN THE PAPER MENTIONED ABOVE.
