>20bp Insertion Mutagenesis - How to?
 

Hi All,

I need to insert 21-30 bps. I inserted 1-2 nucleotides before by simply using primers with these extra bps but 30 bps sounded a little too much to do it with primers. How should I do it? I have these in mind:

1) I can do it with long primers (e.g. 70 bps) with insertion bps in the middle.
2) I can do it sequentially with shorter primers with 5-6 insertions at a time (prefer not to)
3) I can do it with a kit.

I haven't used a kit before and don't know how they work. I m lazy and preferred to ask here instead of reading bunch of different kits' protocols. To be honest I prefer not to buy a kit also.

What is your suggestion? Do you think I can do it with 1st option?

Thanks in advance,
