Hi,
I know that this has been discussed here but I am trying to find hints to
up our transformation efficiency. Right now, we are hovering around
25,000 per ug of DNA. I have heard reports of over a million per ug but
even using the now famous TRAFO method, we were not able to improve things
much, if at all. I know from experience that transformation efficiency is
very strain dependent but we would like to at least get 100,000 per ug
reproducibly, mainly for library screens. Any hints? Electroporation
perhap?
