Thank you for reply!

I re-tranformated novablue cell with pEGFP-N1 without extra band (580
or plasmid with insert and strange band. After miniprep,  that strange
shaw up in all of samples.

Maybe the novablue cell has been contaminated.

I should try  to re-transformate another strain.

Thank you, Guys!
