| − | [http://2010.igem.org/Team:Groningen Team Groningen 2010] reports the usage of this part as a cloning tool. When ligating any part, or part assembly, into any standard backbone that contains this part, the non-restricted and single-restricted backbones that self-circularize will produce red colonies on rich media plates (we use TY). These undesired transformants can than be avoided in the screening for the correct construct. With this method, the backbone desired for a new construct does not need to be purified from agarose gel to decrease the amount of undesired tranformants caused by ligation of the original part present in the backbone.
| |
| − | The amount of incorrect transformants depends, of course, on the ratio of backbone (mixed with J04450) vs. BioBrick insert, the size of the BioBrick insert, and whether the insert is an assembly of two BioBricks. The images below show two ligations with different efficiencies.
