General Description
Recombinant rat CNTF containing 199 amino acids and it shares 83% and 95% a.a.sequence identity with human and murine CNTF.
Background
Ciliary neurotrophic factor (CNTF) is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations.CNTF was initially identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture.Furthermore,the protein is also a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks.In addition,CNTF is useful for treatment of motor neuron disease and it could reduce food intake without causing hunger or stress.
Storage
This lyophilized preparation is stable at 2～8℃,but should be kept at -20℃ for long term storage,preferably desiccated.
Upon reconstitution,the preparation is stable for up to one week at 2～8℃.For maximal stability,apportion the reconstituted preparation into working aliquots and store at -20℃ to -70℃.Avoid repeated freeze/thaw cycles.
Usage
This material is offered by Biorab Biotech for research,laboratory or further evaluation purposes.
NOT FOR HUMAN USE.
Molecular Weight
Approximately 22.7kDa,a single non-glycosylated polypeptide chain containing 199 amino acids.
Purity
＞95% by SDS-PAGE and HPLC analyses.
Source
Escherichia coli.
Biological Activity
Fully biologically active when compared to standard.The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 30ng/ml,corresponding to a specific activity of> 3.3×104IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 2×PBS,pH7.4,2% trehalose.
Endotoxin
Less than 1 EU/μg of rRtCNTF as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom.Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1～1.0mg/mL.Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃.
Further dilutions should be made in appropriate buffered solutions.
