Ciliary Neurotrophic Factor (CNTF) is a member of the IL-6 family of cytokines. CNTF plays a crucial role in developing and maintaining the nervous system, in particular the optic nervous system. It promotes the maintenance, differentiation, and survival of various neurons, glial cells, and retinal cells.

CNTF has been used in vitro to initiate neural induction and differentiation. CNTF can be used to culture primary neurons and glial cells such as astrocytes and Schwann cells. It is also used to culture retinal cells and adipocytes.

Human CNTF has a molecular weight of 22.8 kDa. This protein is animal origin-free, carrier-free, tag-free, and non-glycosylated to ensure its purity with exceptional lot-to-lot consistency. Qk063 is suitable for the culture of reproducible and high-quality neurons and other relevant cells.
