1				PROTEIN WAS DESIALATED WITH NEURAMINIDASE (8 HR AT 37 DEGREES IN 100 MM SODIUM ACETATE, PH 6.5, 10 MG/ML PROTEIN, 0.1 ENZYME UNIT/ML), DIALYZED AGAINST 10 MM TRIS, 25 MM NACL (PH 6.0), AND PASSED THROUGH MONO-Q COLUMN. DESIALATED MATERIAL WAS CRYSTALLIZED BY HANGING DROP METHODS: 17 MG/ML PROTEIN IN BUFFER: 10 MM TRIS,25 MM NACL,1 MM MGCL2,1 MM CACL2, WAS PRECIPITATED FROM 24-27% PEG 3350 IN SAME BUFFER.
