I am using pPICZalfa vector with gene length 1.1 Kb. Currently I am trying for In-vitro multicopy generation (Bgl II - BamHI), but the transformation efficiency in DH5alfa is decreasing as my construct size is increasing. Should I try PTVA method?
Transfection efficiency in general decreases with increasing plasmid size.
Exactly! The plasmid size is increasing at every ligation step.
We are trying to coat some cathode materials on Al-foil ( ex - LiFePO4 , S@CNT, etc). When we coated the Al foil with the cathode (ex - S@CNT) material , the cycling result was annoying. But the...
