As expected.

Electrocompetent cells are just washed cells resuspended in very low 
salt conditions for electroporation by high voltage shock. They couldn't 
possibly behave like chemically competent cells which are prepared very

Are you mixing up what chemically competent cells and electrocompetent 
cells really are?

The problem with being on the cutting edge is that you occasionally get
sliced from time to time....
