This construct has been shown to produce the fluorescent protein mCherry. The plasmid has been transformed into <em>E.  coli </em>TOP10 strain. Starters were grown over night, diluted 1:100,  grown to ~O.D 0.6 and divided into 48 well plates. IPTG was added (to 1mM  concentration) to induce the tac promoter. A control without IPTG was prepared as well. The samples were incubated at 37 degrees for ~3-4.5 hours  before measuring fluorescence in the plate reader. The negative control is pSB1C3  with an MCS insert ([https://parts.igem.org/Part:BBa_K784023 BBa_K784023]).

Experience of BBa_K784011

This construct has been shown to produce the fluorescent protein mCherry. The plasmid has been transformed into E. coli TOP10 strain. Starters were grown over night, diluted 1:100, grown to ~O.D 0.6 and divided into 48 well plates. IPTG was added (to 1mM concentration) to induce the tac promoter. A control without IPTG was prepared as well. The samples were incubated at 37 degrees for ~3-4.5 hours before measuring fluorescence in the plate reader. The negative control is pSB1C3 with an MCS insert (BBa_K784023). The experiment has been conducted in three plasmid backbones: pSB1C3, pSB3C5 and a custom low copy plasmid backbone notated pCP. Since the Top10 strain has low levels of lacI there was little difference with and without IPTG. The measurements taken in the presence of 1mM IPTG are presented in Table 1.
