We are in need of multisite cloning entry vectors. Specifically, pDONR221(P1-P4) and pDONR221(P3-P2). Does someone in Europe have some to send us? I would be ever grateful!!
Hello Anna, I think the best option to quickly get it is to write to a researcher who have used it very recently. A dissertation by Natalie Krieger entitled "expression, localization and interaction studies of plastidic PII protein from Arabidopsis thaliana" made use of that plasmid. You can inquire from them.
