FAQ: NdeI seems to be digesting my DNA correctly, but when I try to ligate it, I obtain no colonies. Is there a potential explanation for what I am observing?

NdeI is a very robust enzyme. If the substrate DNA is digested for extended periods of time, we have found evidence that the enzyme will remove some additional nucleotides. Digestion of DNA with NdeI over 4 hrs is not recommended.
