The present invention concerns a method for folding a Transforming Growth Factor Beta, or a functional analogue thereof, into a dimeric, biologically active form. The method involves adding solubilized, unfolded monomeric growth factor to a solution containing 2-(cylcohexylamino)-ethanesulfonic acid (CHES) or a functional analogue thereof and a low molecular weight sulfhydryl/disulfide redox system. The solution is then incubated under conditions suitable for generating dimeric biologically active Transforming Growth Factor Beta. |
