Premium CytoGrow™ growth factor suitable for stem cell and organoid culture, developmental biology, cell signaling, and tissue engineering research.

CytoGrow™ Recombinant Activin A (Human), CHO, Tag Free

Recombinant human Activin A is a disulfide-linked homodimeric protein belonging to the TGF-β superfamily, produced in CHO cells to ensure high bioactivity and human-like post-translational modifications. This tag-free protein closely mimics the native form, making it ideal for sensitive cell culture and signaling studies.
Activin A plays a critical role in regulating cell proliferation, differentiation, apoptosis, metabolism, and endocrine functions. It is widely used in stem cell research, neuronal differentiation, mesoderm induction, and reproductive biology studies.
