Conjugation

Part:BBa_K873003

Designed by: yue hu   Group: iGEM12_SEU_A   (2012-09-19)

conjugative transfer of RFG

This part contains a reporter gene I13521,combined with OriTR(the R plasmid nic region, is where the relaxosome nicks the plasmid and conjugative transfer by R plasmid machinery begins.)

Function

Once the conjugation take place,the recipient bacterium will obtain the reporter gene which gives
us a signal to distinguish whether the conjugation has happened as well as the conjugation efficiency
easily through observation. In addition, it facilitates the Follow-up experiments on the conjugation
rate, conjugation time, and conjugation efficiency between different strains.

It's show that the conjugation system did work.

Safety

The biobrick safety matters that we may involved in is that we construct a plasmid with the conjugation
function in order to spread our target DNA fragment. For the sake of preventing the plasmid broadcast some
unknown function genes, we ensure that every used liquid medium and gel solid medium are sterile before 
disposal. Well, all the other DNA fragments no matter we used or modified are achieved from the kit plates
or commonly employed in laboratory.
