| Research Abstract |
We investigate the nucleation rate of protein crystals at the interface of solution and porous medium (agarose gel). It was found that 2 ul agarose gel at concentrations of 2.0% (w/v) promoted the number of protein crystals. We also developed a new dispensing system for preparation of the crystallization plates. This technique combined with solution stirring technique improved the crystal quality of a protein complex, thereby solving the crystal structure. The combination with laser irradiation technique demonstrated increase in the nucleation rate. Thus, we propose that a crystallization method using semi-solid agarose is powerful for the screening of crystallization conditions.
