The initial part (BBa_J61025) wasn't giving the resistance, so we remade it from the intermediate CmR-FRT (BBa_J61024). For that we made a PCR with a primer containing the FRT sequence and the RFC10 prefix; this means there is no scar between the first FRT and CmR. This is the reason we encoded it as a new biobrick to differentiate it from BBa_J61025.

The initial part (BBa_J61025) we wanted to use don't confer the chloramphenicol resistance; so we remade it from the CmR biobrick (BBa_P1004). This Cm resistance gene was amplified by PCR using primers containing a mutated FRT sequence (FRT').  As the wild-type FRT sequence contains a Xba1 restriction site, a mutation was introduced to mutate the Xba1 site in order to be able to use this biobrick in iGEM standard 10. This FRT' is the same as BBa_J61020. Since there is no biobrick scar between the FRT' and the CmR gene we encoded it as a new biobrick part compared to BBa_J61025.

Design Notes

The initial part (BBa_J61025) we wanted to use don't confer the chloramphenicol resistance; so we remade it from the CmR biobrick (BBa_P1004). This Cm resistance gene was amplified by PCR using primers containing a mutated FRT sequence (FRT'). As the wild-type FRT sequence contains a Xba1 restriction site, a mutation was introduced to mutate the Xba1 site in order to be able to use this biobrick in iGEM standard 10. This FRT' is the same as BBa_J61020. Since there is no biobrick scar between the FRT' and the CmR gene we encoded it as a new biobrick part compared to BBa_J61025.
