重组人4-1BB配体由大肠杆菌表达系统产生，编码Arg71-Glu254的目的基因在c端以6His标记表达。Accession #: P41273。
别名：Tumor necrosis factor ligand superfamily member 9;
种属：Human
表达系统：E.coli
纯度：还原SDS-PAGE测定大于95%
内毒素：经LAL测试，小于0.1 ng/ug (1 EU/ug)
存储及稳定性：冻干蛋白应在< -20°C保存，但在室温下可保存3周。重组蛋白溶液可在4-7℃下保存2-7天。重组样品的等分液在< -20°C下稳定3个月。
生物活性：肿瘤坏死因子配体超家族成员9(4-1BBL)是单通型II膜蛋白，是肿瘤坏死因子家族成员之一。4-1BBL是一种254种氨基酸的细胞因子，在大脑、胎盘、肺、骨骼肌和肾脏中表达。TNFSF9已被证明除了促进T淋巴细胞增殖外，还能重新激活无能T淋巴细胞。该细胞因子可能在激活诱导细胞死亡(AICD)和t细胞与b细胞/巨噬细胞之间的同源相互作用中发挥作用。它也被证明是CD8 T细胞中最佳CD8反应所必需的，并被认为与T细胞-肿瘤细胞相互作用有关。

| Recombinant Mouse Galectin-1/LGALS1 Protein (E. coli)
Galectin-1/LGALS1 is a member of the galectins. Galectin-1 contributes to different steps of tumor progression including cell adhesion, migration, and tumor-immune escape, suggesting that blockade of galectin-1 might result in therapeutic benefits in cancer. |
| Recombinant Vaccinia virus B18R (Mammalian, C-6His)
B18R is a type I interferon (IFN)-binding protein encoded by the B18R open reading frame in the Western Reserve strain of vaccinia virus. B18R has high affinity for human IFN-alpha and also binds rabbit, bovine, rat, pig, and mouse IFN-alpha and IFN-beta. Secreted B18R binds to uninfected and infected cells. B18R presents at the cell surface and protects cells from the antiviral state. |
| Recombinant Human IL-1R1 (Mammalian, C-6His)
Interleukin 1 receptor, type I (IL-1R1) is an interleukin receptor that belongs to the interleukin-1 receptor family. IL-1R1 is an important mediator involved in many cytokine induced immune and inflammatory responses. It binds to interleukin-1 associates with the corecptor IL1RAP to form the high affinity interleukin-1 receptor complex which mediates interleukin-1-dependent activation of NF-kappa-B, MAPK and other pathways. Recombinant IL1 receptor Type I is a potent antagonist of IL1 action. |
| Recombinant Rat VEGF164 (CHO)
Vascular endothelial growth factor (VEGF/VEGF-A) is originally known as vascular permeability factor (VPF). VEGF-As are endothelial cell-specific mitogens with angiogenic and vascular permeability-inducing properties. It belongs to the PDGF family with a cysteine-knot structure comprised of eight conserved cysteine residues, and reckoned as a potent mediator in the process of angiogenesis and vasculogenesis in either fetus or adult. |
| Recombinant Human DEFB3 (E. coli)
Defensins are cationic peptides. It is an important ingredient of the innate immune system. β-defensins are expressed on some leukocytes and epithelial surfaces. Four human β-Defensins have been identified to date: BD-1, BD-2, BD-3 and BD-4. In addition to their direct antimicrobial activities, they are chemoattractant towards immature dendritic cells and memory T cells. |
