Ultrasonic Ligation

[Dr. Duncan Clark]

Hi All,

I tried the NAR method using a small Ultrasonic cleaning bath (Jencons
Litd., UK, 80W, 40kHz). I tried ligating 1ug EcoR V cut lambda for blunt and
1ug Hind III lambda for sticky ended ligation. In a 15 minute sonication at 16C
no ligation was apparent with the blunt and only slight with the sticky ie
no more than non-sonicated controls. I was not impressed and haven't tried
it again. Maybe my cleaning bath was not the right sort.
