Ideal 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…

The Supercoiled DNA Ladder contains fragments from 2 kb to 10 kb at 1-kb increments and an additional band at 12 kb. Each supercoiled band is at a known concentration, with the 7-kb band at a higher concentration than the others. The resulting brighter band in the middle of the ladder acts as a useful reference point.  Accurate size determination facilitated by evenly spaced bands  Fragments are exact multiples of 1000 bp…
