1	VAPOR DIFFUSION, HANGING DROP	1.5		20MG OF LYOPHILIZED PROTEIN WERE DISSOLVED IN 1ML OF DOUBLE-DISTILLED WATER. USING THE HANGING DROP METHOD WITH DROPS OF 2MUL PROTEIN SOLUTION (20 MG/ML) AND 2MUL RESERVOIR SOLUTION (0.1-0.5 M NACL ADJUSTED TO PH 1.3 WITH HYDROCHLORIC ACID), YIELDED TUFT-SHAPED AGGLOMERATES OF ESSENTIALLY ONE-DIMENSIONAL CRYSTALS. STREAK SEEDING {EM VIA} A CAT WHISKER AFTER TOUCHING THESE AGGLOMERATES GAVE SINGLE CRYSTALS WITH DIMENSIONS UP TO 0.1 X 0.01 X 0.01MM^3
