重组人潜伏性TGF-β1蛋白(RecombinantHumanLatentTGF-β1)是一种重要的多功能细胞因子复合物,由转化生长因子-β1(TGF-β1)成熟肽段与其潜伏相关肽(Latency-AssociatedPeptide,LAP)通过非共价键结合形成。潜伏性TGF-β1是TGF-β1在体内的主要存在形式,能够维持TGF-β1的非活性状态,防止其过早启动,从而精确调控TGF-β1的生物学功能。该重组蛋白通常采用真核表达系统(如CHO细胞或HEK293细胞)制备,确保了其天然构象和生物活性。潜伏性TGF-β1蛋白在体外可被多种因素启动,如酸性环境、蛋白酶切割或整合素介导的机械力作用,释...
