Part:BBa_K777128

Constitutive J23106 promoter

Fig. 1: Overview of our related BioBricks with Anderson promoters and RFP in pSB1C3. (Activity according to Berkeley 2006)

This part is a combination of a constitutive Anderson promoter with the downstream RFP (for more information check out J61002 and J23106) and the plasmid backbone pSB1C3.

Usage and Biology

This construct can be useful in several ways, just like the original part J61002. However, if you plan to send your parts in, they are already in the correct backbone, pSB1C3.

1. You may use this plasmid to insert a promoter of your choice between the XbaI/EcoRI and SpeI sites. This will provide you with a downstream mRFP as a reporter. Look up the specifications for restriction sites here.
2. Furthermore, you can clone a gene of interest downstream of the constitutive Anderson promoters to express it at a desired rate. For this, the SpeI and PstI sites can be used. Look up the specifications for restriction sites here.
3. It can provide a nice selection system for inserting your basic parts into the pSB1C3 vector via the EcoRI/XbaI and PstI site. If you use a construct containing a strong promoter e.g. K777125, colonies containing a self-ligated plasmid after transformation will turn red and you can select for the non-red colonies.
