Figure 4: Expression of the mature peptide portion of cTGF-β1 in vitro.

SDS-PAGE and western blot results using tissue from two testes. Each individual testis are indicated by the black frame. M, protein molecular weight marker; lane 1, lysates of transformed bacteria after induction with IPTG; lane 2, lysates of bacteria transformed with the non-inserted control; lane 3, western blot analysis of recombinant cTGF-β1 using an anti-6 × His tag mouse antibody.
