Applications of BBa_K274003
User Reviews
E. coli turned dark green after transformation of this plasmid. This is unexpected as there is no promoter upstream of the operon.

BBa_K274003 Review No.2 UCL_London, Xiang Chen |
Diagnostic DNA gel was run to test all 4 restriction sites. BBa_K274003 was cut with XbaI, PstI, EcoRI & SpeI, XbaI & PstI. A gel picture is shown as below. This plasmid did not cut with Xba I restriction site in our hands. As such we could not use it to assemble after other parts.

We attempted to try and use the Dark Green E.chromi biobrick (BBa_K274003) in our machine constructs. Although the part was excised using EcoR1 and Spe1 (Fermentas), when we attempted to clone anything in front of this part, by digestion with EcoR1 and Xba1 (Fermentas), we could not obtain any positive clones.
Suspecting that perhaps the restriction sites were not present, we tested the plasmid samples through restriction digests.
Figure 1. E.chromi Dark Green digested with various restriction enzymes to confirm the presence of the Biobrick restriction sites.
As can be noted from Figure 1, the Xba1 site is not present in the Dark Green E.chromi Biobrick part, although the Spe1 and EcoR1 sites are present.
