Lefty-A, or TGF-beta 4, plays a crucial role in determining left-right (L-R) asymmetry in mammalian organ systems. Its implication in endometrial bleeding suggests a potential role in reproductive processes, highlighting its significance beyond embryonic development. Lefty-A/TGF-beta 4 Protein, Human (HEK293, His) is the recombinant human-derived Lefty-A/TGF-beta 4 protein, expressed by HEK293 , with N-6*His labeled tag.
