简单介绍
Recombinant Rat IL-9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 Rat IL-9所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

About this Antibody

Name

Recombinant Rat IL-9 (Recombinant Rat Interleukin-9; rRtIL-9);重组大鼠白细胞介素9

Synonyms

Cytokine P40; HP40; IL-9homolog of mouse T cell and mast cell growth factor 40; interleukin 9; interleukin-9; P40; p40 cytokine; p40 T-cell and mast cell growth factor; T-cell growth factor P40

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 murine TS1 cells is less than 10ng/ml, corresponding to a specific activity of >1.0×105IU/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 0.1EU/μg of rRtIL-9 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

Interleukin-9 (IL-9) is encoded by the IL9 gene and produced by T-cells and specifically by CD4+ helper cells. IL-9 was originally identified as a cytokine found in the conditioned medium of a human T cell leukemia virus type I (HTLVI) transformed T cell line. It functions through the IL-9 receptor, which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. IL-9 can support the growth of IL-2 independent and IL-4 independent helper T-cells. Rat IL-9 has approximately 73% amino acid sequence identity with murine IL-9. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness.

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)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。
       本产品**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。
       为了您的**和健康,请穿实验服并戴一次性手套操作。
