GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥95%(SDS-PAGE)See COA

Biochemical and Physiological Mechanisms
Ciliary neurotrophic factor (CNTF) is a member of the cytokine family. It is a polypeptide hormone that has functions in promoting neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. Its actions appear to be restricted to the

Recombinant Human CNTF Protein (rp302373) - Protein Bioactivity
Measured in a cell proliferation assay using TF-1 cells. The ED₅₀ for this effect is typically 4.8 ng/mL in the presence of 1.0 μg/mL Recombinant Human CNTFR alpha Protein (rp169598).
Recombinant Human CNTF Protein (rp302373) - SDS-PAGE
3 μg/lane of Recombinant Human CNTF Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 27.6 kDa under reducing and 27.6 & 50.2 kDa under non-reducing conditions.
The observation of protein as both dimers and monomers under non-reducing (NR) conditions suggests that a portion of the protein forms dimers. This dimerization may be mediated by (or stabilized by) disulfide bonds (UniProt: P26441).
