I think my attempt was too drawn out in time (even though I did most of it in a cold room at 4C) and this may have led to incorrect folding/degradation. Any advice much appreciated!
Up till now, I've already had seveal attempts. Nothing's wrong except for the activity. And now I am kinda puzzled. May I ask where did you get the pTXB1-Tn5 plasmid? Is it from Addgene?
