I am working on a 26kDa heat shock protein. I understand that to induce a heat shock protein is by heat shock, but what is the best way to induce, express and purify a heat shock protein in a large scale culture?
Heat shock proteins are expressed under cellular stress, high temperatures, low nutrients or oxygen, presence of toxic substances...
Temperature may be the easiest variable to change, but w/o knowledge of the system (bacteria, cell culture, organisms) it is difficult to advice. I'd vary temperature and exposure time and measure the concentration of my POI with ELISA or Western.
