Technical Data
Ciliary Neurotrophic Factor, Recombinant, Human (CNTF)
Molecular Biology Storage: 4C/-20C (No Glycerol)Shipping: Blue Ice
Human ciliary neutotrophic factor (CTNF), is a survival factor for various neuronal cell types believed to prevent the degeneration of motor axons after axotomy.

Recombinant corresponding to human CTNF, 199aa, expressed in E. coli.

Molecular Weight:

Endotoxin: 1EU/ug

The ED50 as determined by the dose-dependent proliferation of human TF-1 cells is 50-150ng/ml.

Suitable for use in Functional Assays. Other applications not tested.

Recommended Dilution:
Functional Assays: 50ng/ml-150ng/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:

Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with 200ul of 5mM sodium phosphate, pH 7.5. Aliquot and store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
