About this Antibody
Name
Recombinant Human CNTF (Recombinant Human Ciliary Neurotrophic Factor; rHuCNTF)；重组人睫状神经营养因子
Synonyms
ciliary neurotrophic factor; HCNTF
Purity
>97% by SDS-PAGE and HPLC analyses.
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 150ng/ml, corresponding to a specific activity of >6.7×103IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4.
Endotoxin
Less than 1EU/μg of rHuCNTF 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.

Cytokine
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. It was initially identified as a trophic factor for embryonic chick ciliary parasympathetic neurons in culture. 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. CNTF is structurally related to IL-6, IL-11, LIF and OSM. All of these four helix bundle cytokines share gp130 as a signal-transducing subunit in their receptor complexes. Recombinant human CNTF containing 200 amino acids and it shares 82% and 83%a.a. sequence identity with mouse and rat CNTF.

保存条件: &苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以**配制成相应浓度的储存液后(请根据产物介绍中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。 注意事项: &苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产物介绍中Reconstitution一栏的信息配制储存液。 &苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;本产物**于专业人员的科学研究用，不得用于临床诊断或**，不得用于食品或药品，不得存放于普通住宅内。 &苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;&苍产蝉辫;为了您的**和健康，请穿实验服并戴一次性手套操作。
