Improved Killswitch (CMV-GMK_TK90-polyA) in RFC[10]

Killswitch (CMV_Killswitch_polyA) in RFC[10]


Since the Killswitchs of Slovenia 2012 BBa_K782063 and Freiburg 2007 BBa_K404113 both contain a forbidden PstI site we wanted to improve this part, because safety mechanisms are of extremely high importance. This restriction site makes a ligation of a BioBrick in the donstream region of this Biobrick impossible. This is why we created the RFC[10] compatible BioBrick BBa_K2170150 (pCMV-GMK_TK90), which carries a CMV promotor in the upstream region of this BioBrick and BBa_K2170060 (pCMV-GMK_TK90-polyA), that contains an additional poly adenylation site for improved mRNA stability. These improved parts are characterized with respect to mRNA expression level and functionality in cell culture.

Quantitative analysis by mRNA measuring of Poly-A-sequence addition showed 4.6-fold higher mRNA stability in comparison to the non-Poly-A-construct. [http://2016.igem.org/Team:LMU-TUM_Munich/Safety More information]
