Protein Expression: basic concepts to new directions


This short workshop will describe many aspects of heterologous expression in E.coli, from choice of construct design through to methods to improve the levels of soluble expression and options for co-expression. In addition, it will also address expression in eukaryotic hosts, including secreted proteins and ECDs, and options for co-expression.

The workshop will finish with a session on protein purification and protein quality and a discussion and problem-solving session using examples brought along by the attendees*.
