| 1 | VAPOR DIFFUSION, HANGING DROP | 7.4 | 293 | 9.3 mg/mL protein in 250 mM NaCl, 25 mM Tris-HCl pH 7.4, 1 mM EDTA, 0.5 mM TCEP, 1.2 mM 3G8, 0.1% w/w V8 protease. 800 nL of protein was mixed with 800 nL of crystallization solution (0.1 M Tris-HCl pH 9.1, 1.5 M diammonium hydrogen phosphate) and incubated over 0.4 mL crystallization solution in 24 well VDX plates. Crystals were cryo-protected with 20% v/v ethylene glycol. |
