Transforming DNA
Tuesday, November 27th, 2007I usually send out plasmid requests as spots on Whatman paper. I draw a circle, pipet several microliters of concentrated DNA into the circle, wrap the DNA in clingwrap and send it off. Lately, I’ve received several “YOU didn’t put any DNA on the paper”. Of course, I didn’t….or perhaps you can’t transform bacteria.
So……
Cut out the circle. Place it in 1.5ml tube, Add enough water so the paper is saturated. Take a microliter of the DNA juice and transform competent cells.
I’d be a little more understanding if the same DNA prep DID NOT transform when I check it before resending it.
I’m sorry, please try again!
