Why do we use 42 degree Celsius heat shock in a transformation?

WebAug 21, 2008 · The heat shock does open the pores (made by the preparation of competent cells) and gets the plasmid to enter the cell. Placing the cells on ice after the shock closes the pores and prevent the plasmid to escape. That sounds very similar to what I've read, and I think that's more or less the answer.
