Summary of the effects of heterogenous nucleating agents.

For each protein/heterogeneous nucleating agent pair and the sum over all proteins, the number of new and missing crystallization conditions (“+” and “−”, respectively) is shown, relative to the no-nucleant control. For the no-nucleant control, the total number of crystallization hits is shown. The total effect of the nucleating agent, relative to the no-nucleant control, is shown in the last two rows. “ND”, not determined.
