Hy everyone, I have been working hard to clone an Arabidospis promoter in the pDONR p4-p1,r Entry Vector, but it didn't work until now !!!
When checking my primers, I obseved that Attb4 primer lacks a G nucleotide at the 5-prime (only 3 Gs instead of 4 Gs as recomended in the Gateway Manual). My questions: Is there a problem with this? BP Clonase reaction could be affected if you have this situation in your PCR product?
I need some help, I dont know what I do. I obtained some positives clones when plating in LB Kanamycin 50 ug/uL, but the clones were negative for insert by PCR or Digestion.
Thak you so much !!
