I have a problem with cloning pHannibal cassette in pART27vector....I cut phannibal cassette and open pART27 with NotI and seems to be OK....after i treat the pART27 with CIAP, extract all the two bands from agarose gel...ligate and cloning with eclectroporation, the ligation in E.coli DH5alfa...after i select on antibiotic Kanamicin 50ug/ml...but not works....There's anyone that can help me????

See my reply to your similar post in the Plasmid/Cosmid/BAC/PAC topic of the molecular biology forum:

Have you tried lower concentrations of antibiotics during your selection step. Also, have you confirmed any surviving culture after your electroporation step. It may be possible that your culture is no longer viable. In such case, you may need to repeat this cloning step.
