X-RAY DIFFRACTION ? 298.15 For crystallization purposes, uPA was co-incubated with AB2 in a 1:1 stoichiometric ratio for 1h and co-purified using size-exclusion chromatography. The complex co-eluted was concentrated to 15 mg/mL.Crystallization drops were produced by mixing 0.1 uL of uPA-AB2 solution with 0.1 uL of the respective crystallization solution. A single crystal was produced using a solution containing 0.2 M diammonium hydrogen citrate (Salt) and 20 percent PEG 3350 and incubating the experiment for 14 days at room temperature.
