简单介绍
Recombinant Murine IL-1RA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 Murine IL-1RA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 Protein

Name

Recombinant Murine IL-1RA (Recombinant Murine Interleukin-1 Receptor Antagonist Protein; rMuIL-1RA)Recombinant Mouse IL-1RA ; 重组小鼠白细胞介素1受体拮抗剂

Synonyms

IL-1F3; IL1RN; DIRA; ICIL-1RA; IL1F3; IL1RA; IL-1ra; IL-1ra3; IL1RN; IL-1RN; interleukin 1 receptor antagonist; IRAP; MVCD4

Purity

>97% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by inhibiting IL-1α-dependent proliferation of murine D10S cells is less than 50ng/ml, corresponding to a specific activity of >2.0×104IU/mg in the presence of 50pg/ml rHuIL-1α.

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 rMuIL-1RA 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.

Category

Cytokine

Background

IL-1RA was initially called the IL-1 inhibitor which is encoded by the IL1RN gene and it is a member of the interleukin 1 cytokine family. IL-1RA is secreted by various types of cells including immune cells, epithelial cells, and adipocytes. IL-RA has functions of inhibiting the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. IL-1RA is also used in the treatment of rheumatoid arthritis, an autoimmune disease in which IL-1 plays a key role. The murine IL-1RA is a single non-glycosylated polypeptide chain containing 152 amino acids and it has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. The protein shows 26% amino acid homology to IL-1β and 19% homology to IL-1α. It also shares 90%a.a. sequence identity with rat IL-1RA.

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。
