GFP/RFP reporter (Forward/Reverse) with random 500bp spacer

This part contains two fluorescent protein expression units (for RFP and GFP) with promoters, RBSs, CDSs, and terminators, GFP facing forward and RFP facing backward, with a random 500bp spacer between the two reporters. Parts were amplified from iGEM Registry (BBa_J04450 (RFP) and BBa_I13522 (GFP)) and assembled with golden gate assembly to make the full part. This composite part is designed to demonstrate the effect, if any, of a 500 bp spacer between genes on supercoiling generated by the two genes, and therefore on interference between the genes.

This part is one of an 8-plasmid set (K2145000, K2145001, K2145104, K2145105, K2145124, K2145107, K2145126, and K2145127). Other plasmids in this set are similar, but have GFP and RFP expression cassettes pointing in different directions and in different arrangements on the plasmid. Different arrangement and orientations are expected to generate different patterns of supercoiling, which translates to different patterns of expression in RFP and GFP if supercoiling creates interference between the two.

-This part contains two fluorescent protein coding sites (RFP and GFP) and was assembled using Golden Gate Assembly. In order to make the plasmid, parts were taken from iGEM Registry (BBa_J04450 (RFP) and BBa_I13522 (GFP)) along with a 500 base pair "spacer" part derived from different backbones, and a pSB1C3 backbone assembled to make the final part. It can be used to express both GFP and RFP proteins.
