 Phosphorylating Oligos Heya dudes, i am in the process of phosphorylating some oligos using the enzyme PNK. I added the following:
However it seems my Phosphorylation protocol failed. All of cloning were were negative!  . What should i do?My ideas it may be the ATP gone old/bad? I was using ATP (100mM) from which was prepared as a solution from Roche. The new ATP comes as a powder, and I make 100mM solution by dissolving it in water? is this the problem? thnx in advance        |
