These are forums for open discussion of protein-related challenges, and not sales opportunities. We emphasize that these breakout groups are for interactive discussions among scientists and are not meant to be, in any way, a corporate or product discussion. Topics can be limited to one protein area or may address issues which cross over the borders between pipeline conference topics. Moderators should be well-versed in the topic area and able to keep the discussion focused and productive. BuzZ Sessions are IN-PERSON ONLY.
