Sebastiano, I have had really nice success by mixing initial crystallization hits back in to sparse matrix screen conditions. My personal favourite is using the Wizard screens. http://www.rigakureagents.com/p-1-wizard-classic-crystallization-screen-series.aspx I found 75% of the

Hi Sebastian, you're thinking about local sparse matrix screening. I've done this at a 90:10 ratio. Majeed, S., Ofek, G., Belachew, A., Huang, C.C., Zhou, T., and Kwong, P.D. Enhancing protein crystallization through precipitant synergy. Structure. 2003; 11: 1061–1070 All best. Andreas On

Dear all, I recall a paper (or was is a talk at a conference?) describing the optimisation of initial hits of crystallisation by using a standard screen kit as additive. Something like setting the tray using the initial crystallisation hit condition in the reservoir and mixing 75% of the hit
