Unreliable Fluorescence Screening for Gibson Assembly

A laboratory encountered issues with fluorescence screening for Gibson assembly, where E. coli with inserted pBad+DsRed fluoresced similarly to lacl+GFP under blue light, leading to inconsistent results. The team struggled to understand the cause of 'false fluorescence' and a 'blue halo' around colonies. This challenge highlights the need for more reliable methods to verify successful insertions.
