Here we introduce a fast, cost-effective, and highly efficient method for production of soluble fluorescent proteins from bacteria. The method does not require optimization and does not use isopropyl β-d-1-thiogalactopyranoside (IPTG) induction. The method relies on uninduced expression in the BL21-Gold (DE3) strain of Escherichia coli and yields large amounts (up to 0.4 μmol) of fluorescent protein from a 250-ml culture. This method is much simpler than published methods and can be used to produce any fluorescent protein that is needed in biomedical research.
