Preliminary X-ray diffraction analysis of human chorionic gonadotropin.

چکیده
Hexagonal bipyramidal crystals of deglycosylated human chorionic gonadotropin have been grown using the method of vapor diffusion against ammonium sulfate. These crystals grow to nearly 0.4 mm along each axis, diffract to better than 3.5-A resolution and are relatively stable to irradiation. The crystals belong to the hexagonal space group P6(1)22 or enantiomer, and have unit cell parameters a = b = 88.7 A and c = 177.3 A.
