About this Antibody
Name
Recombinant Human sTNF RII/TNFRSF1B (Recombinant Human soluble Tumor Necrosis Factor Receptor Type II/TNFRSF1B; rHusTNF RII/TNFRSF1B)；重組人可溶性腫瘤壞死因子受體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.

保存條件: -20℃或更低溫度保存，至少一年有效。由于蛋白的每次凍融均會引起部分失活，所以**配制成相應濃度的儲存液后(請根據產品簡介中Reconstitution一欄的信息配制儲存液)，須分裝后-20℃或更低溫度凍存，以避免反復凍融。 注意事項: 由于有些塑料管壁對某些蛋白有較強的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA等)的主要作用是預先封閉塑料管壁上的蛋白結合位點，使細胞因子或重組蛋白不會粘附于管壁。所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。 本產品**于專業人員的科學研究用，不得用于臨床診斷或**，不得用于食品或藥品，不得存放于普通住宅內。 為了您的**和健康，請穿實驗服并戴一次性手套操作。
