Abstract
A ciliary neurotrophic factor (CNTF), particularly sciatic nerve CNTF(SN-CNFT) is claimed. The SN-CNTF described herein is a single protein species and has a specific activity that increased to greater than 25,000-fold from crude extract. Amino acid data for this SN-CNTF is also provided. In addition, methods for using this data for providing SN-CNTF probes and for screening cDNA and genomic libraries are also provided. Recombinant-DNA methods for the production of SN-CNTF are described. Nucleic acid sequences encoding rabbit and human CNTF are provided. A recombinant expression system is provided for producing biologically active CNTF.
