How does heat shock help transformation

WebHeat shock results in an altered configuration of proteins. This activates the heat-shock transcription factor (HSF), which then activates genes coding for heat-shock proteins (HSPs). HSPs have the general task of correcting the abnormal situation caused by HS-damaged proteins (see Lindquist and Craig, 1988 ). WebEssentially, heat shock bacterial transformation is centered on exposing bacterial cells (e.g. E. coli) to a heat shock. This refers to a sudden or rapid increase in temperature resulting in pore formation through which the DNA material (e.g. plasmids) can enter the cell.

Bacterial Transformation - Gene Transfer, Heat Shock, Vs …

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.
