Microbial engineering

The Samuelson lab is primarily focused on tailoring E. coli strains and expression systems to maximize the expression and purification of individual proteins of interest.


NiCo21(DE3) is a BL21(DE3) derivative designed for improved expression and purification of His-tagged proteins.
