 Dephosphorylation of Insert Hi, By mistake I added Shrimp Alkaline phosphatase to my insert digestion and not to my plasmid digestion. My plasmid is ~7kb and insert is ~550bp, and they are digested with 2 different restriction enzymes HindIII and NdeI. Should I go ahead and ligate and transform or is it not worth it? Thanks  |

| Re: Dephosphorylation of Insert Hi Hannah, The dephosphorylation reaction is done with the plasmid to prevent vector from re-sealing to itself during the ligation. If you added it to your insert by mistake, you might still be ok because the plasmid (vector) should still be phosphorylated. It's worth a try. Sorry if this is too late but hope it helps for future reference! |
