About this protein
|
Name
|
Recombinant Human IL-31 (Recombinant Human Interleukin-31; rHuIL-31);重组人白细胞介素31
|
Synonyms
|
IL-31interleukin-31; interleukin 31
|
Purity
|
>97% by SDS-PAGE and HPLC analyses.
|
Biological Activity
|
Fully biologically active when compared to standard. The specific activity is determined by inducing STAT3 activation using human U-87 MG cells. 5ng/ml of rHuIL-31 can effectively induce STAT3 activation.
|
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 rHuIL-31 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.

Background
|
Human IL-31 gene is located on Chr.12. It expresses the IL-31 protein at low levels in the type 2 helper T cells, which exits in testis, bone marrow, skeletal muscle, kidney, colon, thymus, small intestine and trachea. This protein shares several structural and functional characteristics with IL-6, Oncostatin M, LIF, and Cardiotrophin-1. IL-31 signals through IL-31 receptor A and oncostatin M receptor subunits and can activate STAT3 through receptors and maybe involve in skin immunity. It regulated immune responses have been implicated in skin physiology and inflammatory skin diseases. Human IL-31 shares 24%a.a.sequence identity in the mature protein with mouse IL-31.

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,所以首次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。
