+ | In order to excise the chloramphenicol resistance cassette from the integrants in E.coli genome we transformed the cells with a plasmid (pCP20 plasmid) carrying the gene encoding for the flippase protein. This protein is able to cut fragment between two FRT flanking sequences. pCP20 was transformed in MC43-a and MG43-a and plated on LB+Amp agar plate. | ||

+ | PCR from colony for I55 (eleven colonies were picked). | ||

+ | [[Image:UNIPV10_02_10_2010_I55_screening.jpg|thumb|200px|center|I55 colony PCR screening.]] | ||

+ | We decided to make glycerol stock for I55-1. Inoculum into 5 ml LB+Amp of the positive culture that was let grow ON at 37°C, 220 rpm. | ||

+ | 1,5 hours E-P digest (for screening) and gel run | ||

+ | |||
+ | As you can see they are (except for I73-6) all positive. So we stocked I73-1 and stored it at -80°C. | ||
+ | |||
+ | ---- | ||
+ | Transformation of I74 and INTEIN_C3 (1ul) in ''E. coli'' TOP10. They were plated on LB+Amp100 and LB+Cm34 agar plates respectively. They were let grow ON at +37°C. | ||

+ | Inoculum of I55-1 into 5 ml LB+Amp. ON growth at +37°C, 220 rpm. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | 3 colonies each plate were picked from MC43_flip and MG43_flip plates and inoculated in 5 ml of non selective LB. To confirm the loss of the chloramphenicol resistance cassette and of the pCP20 plasmid, each colony was inoculated also in 5 ml of LB+Cm12.5 and 5 ml of LB+Amp. | ||

+ | Glycerol stock for: | ||
+ | *I55-1 | ||
+ | *IC-1/2/3/4-4C5 | ||
+ | |||
+ | ---- | ||
+ | Pick of a single non-red colony of INTEIN_C3 and inoculum into 5 ml LB+Cm34. Sample was let grow ON at +37°C, 220 rpm. | ||
+ | |||
+ | ---- | ||
+ | Miniprep and quantification of: | ||
+ | *I55-1: 57,4 ng/ul | ||
+ | *I55-1bis: 79,6 ng/ul | ||
+ | |||
+ | I55-1bis was digested E-S for about three hours and than gel run/cut. | ||
+ | |||
+ | ---- | ||
+ | |||
+ | Colony PCR for I74-1..6. | ||
+ | |||
+ | ---- | ||
+ | Gel run for PCR samples and I55 (E-S) and cut for this one. | ||
+ | [[Image:UNIPV10_03_10_2010_I74_screen_I55_cut.jpg|thumb|200px|center|I74 screening and I55 E-S cut.]] | ||
+ | Very bad PCR. We performed a massive PCR from colony during the night (I74-7..24), we ran it the following day. | ||
+ | |||
+ | Gel extraction and quantification: | ||
+ | *I55 (E-S): 5,0 ng/ul | ||
+ | |||
+ | Ligation of I55 (E-S) with already available DNA: | ||
+ | *I75: I55 (E-S) + I37 (E-X) | ||
+ | *I77: I55 (E-S) + I57 (E-X) | ||
+ | ---- | ||
+ | Inoculum of I35 (last quantification after gel extraction was too poor; we will digest it again E-P) and I54 into 5 ml LB+Amp: ON growth at +37°C, 220 rpm. | ||
+ | |||
+ | ---- | ||
+ | Each culture of MC43_flip and MG43_flip in selective LB didn't grown, confirming the loss of pCP20 plasmid and of the chloramphenicol resistance cassette integrated into the E.coli genome. | ||
