    >98% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 23.74 kDa.
    The protein migrates as 25 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to induce proliferation in TF-1 cells. The ED₅₀ for this effect is <0.15 μg/mL.

    Endotoxin Level

    <0.1 EU per 1 μg of the protein by the LAL method.

  • Form

    Lyophilized

• Background

  • Background

    Ciliary neurotrophic factor (CNTF) is the member of IL-6 cytokine family and expressed in the nervous system. CNTF is 22.9 kDa neurotrophic factor containing 200 residues, which shows multiple effects in vertebrate retinogenesis. Besides, CNTF acts as a promoter that not only accelerates adult neurogenesis but also increases the survival of neuron after injury. On the other hands, reducing number of hippocampal GABAergic interneurons, as well as 5-HT levels and 5-HT1A receptor expression has been found in CNTF knockout female mice, indicating that CNTF may influence affective behavior in females by regulation of neurotransmission.

• Instruction

  • Reconstitution

    It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

    Shipping

    The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

  • Stability & Storage

    This product is stable after storage at:

    • -20°C for 12 months in lyophilized state from date of receipt.
    • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

    Avoid repeated freeze/thaw cycles.
