Figure 2 Escherichia coli clones on Luria–Bertani AMP plates with blue-white screening using the pGEM-T Easy vector. This approach is based on detection of the vector that has been ligated to the target gene in the presence of an X-Gal analogue and IPTG. White colonies indicate successful ligation of the insert with the vector; blue colonies indicate no ligation.
