Hi everyone,

I’m excited to share that our new open-source, free-use E. coli expression strain developed through the OpenBioMAPS project has successfully produced mCherry fusion proteins. Preliminary benchmarking against BL21(DE3) indicates that this strain may yield higher amounts of protein after overnight induction with IPTG.

Looking forward to further testing and refining its performance. Feedback and collaboration are very welcome!

Thanks,

Aaron

Dear Aaron,

This is great work. I would like to get some of the opensource E coli. Could you point me in how might be able to get some cell. Thank you so much. You can also reach me at (erosca@ashesi.edu.gh).
Best wishes,
Elena
