It was prepared by modifications of the method described by Zubay et al (1980). '''''E. coli'' strain B''' deficient in OmpT endoproteinase and lon protease activity was used.
The simple constitutive gene expression device [https://parts.igem.org/wiki/index.php/Part:BBa_i719005 BBa_I719005] has been used to characterize this cell-free chassis
