简单介绍
Recombinant Human CNTF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。Recombinant Human CNTF所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

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.

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:
-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(请根据产品简介中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:
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。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
