生物活性的

Because the dimeric form is the active form to exert its biological activities, many trials failed to express TGF β s in prokaryotic systems because of their complex folding manner and disulfide patterns. In 1991 Cerletti and coworkers from Ciba-Geigy Corporation in Switzerland successfully finished the functional expression of human TGF β 2 in bacteria, but the details are protected by the patent.

由于双体是其发挥生物活性的形式，TGF β复杂的折叠方式和二硫键配对使其早期原核基因工程研究都以失败而告终。1991年，瑞士Ciba-Geigy公司的Cerletti等成功完成了人TGFβ2基因的细菌表达，但其技术细节被专利加以保护。
