About this protein

Name

Recombinant Human IL-17B (Recombinant Human Interleukin-17B; rHuIL-17B)；重组人白细胞介素17B

Synonyms

Cytokine Zcyto7; cytokine-like protein ZCYTO7; IL-17Binterleukin-17 beta; IL20; IL-20interleukin-17B; interleukin 17B; interleukin 20; Interleukin-20; MGC138900; MGC138901; neuronal interleukin-17 related factor; Neuronal interleukin-17-related factor; NIRF; ZCYTO7interleukin-20

Purity

>95% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by inducing IL-8 secretion of human HepG2 cells is less than 1.0μg/ml, corresponding to a specific activity of >1000IU/mg.

Physical Appearance

Sterile Filtered lyophilized (freeze-dried) liquid-like powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, with 0.1% Tween-20 and 3% Trehalose.

Endotoxin

Less than 0.1EU/μg of rHuIL-17B 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

IL-17B, also named IL20, NIRF and ZCYTO7, is belonging to the IL-17 family and it stimulates the release of tumor necrosis factor alpha and IL-1-beta from the monocytic cell line THP-1. IL-17B mRNA is expressed in adult pancreas, small intestine, and stomach. The IL-17 family is comprised of at least six proinflammatory cytokines that share a conserved cysteine-knot structure but diverge at the N-terminus. IL-17 family members are glycoproteins secreted as dimers that induce local cytokine production and recruit granulocytes to sites of inflammation. IL-17B binds the IL-17B receptor, but not the IL-17 receptor; it is most homologous with IL-17D, which is expressed by resting CD4+ T cells and CD19+ B cells. This cytokine was reported to stimulate the release of TNF alpha (TNF) and IL1 beta (IL1B) from a monocytic cell line. Immunohistochemical analysis of several nerve tissues indicated that this cytokine is primarily localized to neuronal cell bodies.

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。
本产品在冻干时添加了海藻糖作为保护剂，此时冻干后本产品看起来仍然像是液体，属于正常现象。在冻干工艺上，海藻糖作为常用的冻干保护剂，可显著阻止蛋白质二级结构的改变，防止冻干过程中的蛋白变性。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
为了您的安全和健康，请穿实验服并戴一次性手套操作。
