1 | VAPOR DIFFUSION, SITTING DROP | 8.5 | 300 | Well condition: 0.3 M magnesium formate plus 0.1 M TrisHCl. Protein: The insulin analog was prepared in a mixture that also contained receptor fragments: 5 mg/ml (IR310.T).Fv83-7 in 10mM HEPES-NaOH (pH7.5) + 0.02% NaN3 plus three mol equivalents of the IR-A alphaCT peptide 704-719 plus 1.8 mol equivalents of the analog. The analog crystallized in isolation from the receptor fragments and it is not known whether the receptor fragments aided crystallization |
