I am using a Qiagen Midi Prep kit. I have done lots of mini preps before but this is my first Midi prep. I have used mini preps on the exact same plasmid with no problem.

14 QIAprep Miniprep Handbook 06/2005. Using LyseBlue reagent. Using a simple visual identification system, LyseBlue reagent prevents common handling errors that lead to inefficient cell lysis and incomplete precipitation of SDS, cell debris, and genomic DNA. Plasmid DNA encoding constitutively expressed GFP (pEGFP-C2) was prepared using either Monarch Plasmid Miniprep Kit or Qiagen QIAprep Spin Miniprep Kit. Four different cell lines (Cos-7, HEK293, HeLa, and Huh-7) were grown to 80-90% confluence and transfected with 100 ng of each plasmid, in complex with 0.3 μl Lipofectamine 2000, and 10 μl ...

I tried different commercial kits (sigma qiagen, genscript) and with all same results. Plasmid is there but in very low concentration. other construicts that I worked in parallel are ok.. yield is ok, but with this particular one (15000 kb) seems that its spit out of cells if overgrown. Today i did maxi from 250 ml OD 0.45 and pellet.. again ...
