Protein Expression in Bacteria Over the years, Creative Biolabs has developed BacTEC ™ and FoldEZ™ technologies to tackle hard-to-express and hard-to-dissolve proteins. With BacTEC™ technology, the expression level can be greatly improved for almost all of the proteins.
Controlled expressionfor maximum yields The pBAD Expression System helps you overcome two of the most common problems for heterologous protein expression in bacteria:
Optimising Expression in Bacteria. Generating soluble, active protein is a major challenge for recombinant protein production in E. coli. Over-expression of eukaryotic proteins often leads to the formation of insoluble aggregates known as inclusion bodies.
