Hello to everyone!

I'm conducting a study with plasmid DNA and need one that is really small.
Could someone tell me if there are plasmid backbones,
either with an insert or not, with sizes equal or lower than 2000bp.
And a place where i can purchase it, i've tried to search  but the smallest
one i could find was pUC18.
Thanks in advance for your help.

Kind regards

The plasmid pSB1A2 is 2057 bases.  It could probably be shortened by some amount without loss of function.
