Catalogue number



Cerebral neurotrophic factor, arginine-rich, mutated in early stage tumors-like 1, Conserved neurotrophic factor, ARMET-like protein 1, ARMETL1.


CDNF is a member of the ARMET family and acts as a trophic factor for neurons. CDNF inhibits the (6-OHDA)-induced degeneration of neurons. When CDNF controlled after 6-OHDA-lesioning, it reestablishes the function and inhibits the degeneration of neurons in substantia nigra. CDNF is universally expressed in neuronal and non-neuronal tissues. The highest levels in the brain are found in the optic nerve and corpus callosum.


CDNF Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 161 amino acids and having a molecular mass of 18.5kDa.
The CDNF is purified by proprietary chromatographic techniques.


Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.


CDNF protein was lyophilized from a 0.2µm filtered concentrated solution in 1xPBS, pH 7.4.


It is recommended to reconstitute the lyophilized CDNF in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized CDNF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CDNF should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.


Greater than 96.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Amino acid sequence


Biological Activity

The ED50 as determined by its ability to stimulate the proliferation of rat C6 cells is 15-25µg/ml, corresponding to a specific activity of 40-67units/mg.

Cerebral Neurotrophic Factor Human Recombinant: A Leap Forward in Neurobiology


The field of neurobiology is replete with wonder, particularly due to the influential role of neurotrophic factors. These essential proteins, responsible for the survival and growth of neurons, have become a focal point in modern research. Among these, the Cerebral Neurotrophic Factor (CNF) stands out, offering novel insights and potential breakthroughs in our understanding of neurological health.


Enter the world of bioengineering, a scientific arena where we have successfully replicated CNF, leading to the birth of Cerebral Neurotrophic Factor Human Recombinant (CNF-HR). This is a massive step towards conquering neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, conditions that have perplexed scientists and clinicians for decades.


The extraordinary capacity of CNF-HR lies in its dual functionality - it acts as a defender and a promoter. It defends neurons from harmful degenerative processes while promoting their growth and development. Picture a devoted gardener who tirelessly protects his garden from pests and nurtures the growth of each plant. In this context, the brain is the vibrant garden, and the neurons, the delicate plants we must care for.


Although this scientific breakthrough sparks enthusiasm, it's crucial to remember the challenges that lie ahead. The path to determining the most effective method of delivering CNF-HR to the brain, identifying the optimal dosage, and monitoring potential side effects is a winding one. Nevertheless, with continuous research and relentless scientific curiosity, we are optimistic about overcoming these challenges.


In conclusion, the development of CNF-HR is a significant milestone in the fascinating journey of neurobiology. Its potential to change the trajectory of treating neurodegenerative diseases and enhancing our understanding of neuronal function is tremendous. While the journey is strewn with complexities, the potential rewards we stand to reap promise a future where neurodegenerative diseases could be effectively managed or even cured.
