dear Maria, we routinely use Mosquito for MMS, the ratio works the best: 100nl protein + multi-aspirate mode x (15nl seeds + 85nl reservoir solution). best regards, alexey Alexey RAK

The reason for doing this was two-fold: I) ratio protein/reservoir is similar to the condition that generated the seed stock II) a deliberate bias toward the initial condition is given I) and II) might not always be helpful and possibly other ratios should be explored.

Which way is the optimal way of adding seed solution to sitting drops on an MRC plate? Is it better to add 100 nl protein + 10 nl seed solution + 100 nl reservoir solution or to add concentrated seed solution (1 microliter) directly to the reservoir solution and then pipett 100 nl protein + 100 nl reservoir solution.
