Proteins expression-temperature inducible vs IPTG inducible system - (Dec/08/2005 )

hi every body.
I usually induce the expression of my proteins using the IPTG system.
I recently found that the induyction can also be done a temerature inducivble system .
Can some one please tell what kind of advantage (/or disadvantages) will the temperature inducible system have comparing to the IPTG inducible system?
thank you a lot


they say that one advantage of using temp inducible is that it is a cheaper alternative compared to using IPTG


thank you for answearing me.
