CDNF is a secreted neurotrophic factor that is expressed in brain, neuronal and certain non- neuronal tissues. It has been shown to promote survival, growth and function of dopamine specific neurons. CDNF and its structural homolog MANF, each contain an N-terminal saposin- like lipid binding domain, and a carboxyl-terminal domain, which is not homologous to previously characterized protein structures. CDNF and MANF can prevent 6-OHDA induced degeneration of dopaminergic neurons by triggering survival pathways in a rat experimental model of Parkinson disease. Recombinant human CDNF is an 18.5 kDa protein consisting of 162 amino acids including 8 cysteine residues.
Human CDNF expressed in E.coli
CAT# CSC-CTK0320-25 (25 μg); CAT# CSC-CTK0320-125 (125 μg)
Greater than 98% as determined by SDS-PAGE and HPLC analyses.
Determined by its ability to stimulate the proliferation of rat C6 cells. The expected ED50 for this effect is 15-25 μg/ml.
Less than 1 EU/μg.
Sterile-filtered through a 0.2 micron filter and ly ophilized from 10 mM sodium phosphate Buffer (pH 7.0).
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1 - 1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored dessicated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at –20°C. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze / thaw cycles.
