E activated heterotetrameric TLR4/MD-2 complex and thus does not trigger the endotoxic response. In addition, the oligosaccharide chain is deleted, making it easier to remove the resulting lipid IV A from any downstream product. Figure 1.

For most simple plasmid transformations, it is not necessary to harvest bacteria at early to mid log phase. However, if the transformation efficiency is low, dilute 1 ml of the overnight culture in 20 ml of LB and grow at 37 °C with shaking until the OD600 measures between 0.4 and 0.6 (1–1.5 h).
