简单介绍
Recombinant Rat IL-33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-33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-33 (Recombinant Rat Interleukin-33; rRtIL-33);重组大鼠白细胞介素33

Synonyms

Interleukin-33; IL-33; Il33

Purity

>95% 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 D10S cells is less than 0.5ng/ml, corresponding to a specific activity of >2.0×106IU/mg.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in 20mM Tris, 300mM NaCl, pH8.5.

Endotoxin

Less than 1EU/μg of rRtIL-33 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-33 (IL-33), also known as NF-HEV and DVS 27, is a cytokine belonging to the IL-1 superfamily. It is also a proinflammatory protein that may regulate gene transcription and it induces helper T cells, mast cells, eosinophils and basophils to produce type 2 cytokines. The induction of type 2 cytokines by IL-33 in vivo is believed to induce the severe pathological changes observed in mucosal organs following administration of IL-33. IL-33 is constitutively expressed in smooth muscle and airway epithelia and it binds to a high-affinity receptor family member ST2. In vivo administration of mature IL-33 promotes increased production of IL-5, IL-13, IgE, and IgA, as well as splenomegaly and inflammatory infiltration of mucosal tissues. Recombinant rat IL-3 contains 156 amino acid residues and it shares 59%a.a. and 90% sequence identity with human and murine IL-33.

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。
