LOBSTR E. coli Expression Strain for One-step Purification
KerafastIdeal for low-expressing protein targets, the LOBSTR E. coli expression strain allows for one-step polyhistidine-tag affinity purification by eliminating the two major E. coli contaminants.
Traditionally, a major drawback to using polyhistidine-tag affinity purification for proteins expressed in E. coli is contamination resulting from the presence of two naturally histidine-rich proteins in E. coli, ArnA and SlyD. LOBSTR (l…
