About this Antibody
Name
Recombinant Human sTNF RII/TNFRSF1B (Recombinant Human soluble Tumor Necrosis Factor Receptor Type II/TNFRSF1B; rHusTNF RII/TNFRSF1B)；重组人可溶性肿瘤坏死因子受体II型/TNFRSF1B
Synonyms
CD120b; TNFRSF1B; CD120b; CD120b antigen; Etanercept; p75 TNF receptor; p75TBPII; p75TNFR; soluble TNFR1B variant 1; TNFBRp80 TNF-alpha receptor; TNF-R2; TNFR2TNFR1B; TNF-R75; TNFR80; TNF-RII; TNF-R-II; TNFR-II; tumor necrosis factor beta receptor; tumor necrosis factor binding protein 2; Tumor necrosis factor receptor 2; tumor necrosis factor receptor superfamily member 1B; tumor necrosis factor receptor superfamily, member 1B; Tumor necrosis factor receptor type II
Purity
>97% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The ED50 as determined by its ability to inhibit the TNF-α mediated cytotoxicity in the L-929 cells is less than 0.2μg/ml, corresponding to a specific activity of >5000IU/mg in the presence of 0.25ng/ml of rHuTNF-α.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered solution in PBS, pH7.4.
Endotoxin
Less than 0.1EU/μg of rHusTNF RII/TNFRSF1B 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
Tumor Necrosis Factor Receptor-I (TNF RI, also known as XY5/p60) and TNF RII (also known as p75/p80) are both high affinity receptors for TNF-alpha and -beta, potent mediators of multiple aspects of inflammatory immune responses. Both RI and RII are prototypic members of the TNF receptor superfamily and have been designated TNFRSF1A and TNFRSF1B, respectively. Whereas all cell types are thought to express TNF RI, TNF RII expression is limited primarily to hematopoietic cells and cells of the immune system. Most of the biological functions of TNF are mediated via TNF RI. Soluble forms of both TNF RI and TNF RII, generated as a result of proteolytic cleavage of the extracellular domains, have been detected in vivo in various biological fluids. The soluble TNF receptors can bind TNF with high affinity and functions as TNF antagonists.

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**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。
