Test1. Conjugation between E.coli HB101 and Top10

Test1. Conjugation between E.coli HB101 and Top10 We do conjugation experiment between HB101 and Top10 to test the conjugation ability of OriTR (BBa_J01003). We got a special strain from other lab which is sensitive to Streptomycin, while Top10 has streptomycin resistance. In order to test BBa_J01003 better, we ligate OriTRP4 with the report gene RFP. After conjugation, we pick the red colonies by LB medium with resistance.

Conjugation between E.coli HB101 and Top10

	HB101(double plasmids system)	chloramphenicol	chloramphenicol & streptomycin
Conjugation (HB101 and Top10 mixed system)	White colony	Red colony	Red colony
Top10(no plasmid)	White colony	No colony	No colony
HB101(double plasmids system) & streptomycin	No colony	Red colony	No colony

Table.1 We designed a orthogonal experiment, it is showed in the table. The first column shows the strains used in coating, and the first row shows the antibiotics added in medium. Besides, the table shows the result ideally. The second row proves that HB101, plasmid RP4 and the backbone pSB1C3 don’t contain streptomycin resistant gene. The third row proves that Top10 is sensitive to chloramphenicol. And the forth row proves that Top10 can receive the mini plasmid after conjugation.
