Biotinylated Human IL-21 Protein, Fc Tag, Avi Tag (Avitag™)_详细资料

产品信息 供应商： ACROBiosystems 英文名： Biotinylated Human IL-21 Protein, Fc Tag, Avi Tag (Avitag™) 保存条件： -20 规格： 25ug/200ug 规格： 25ug 产品价格： ¥3500.0 规格： 200ug 产品价格： ¥13800.0 内毒素: Less than 1.0 EU per μg by the LAL method. 纯度: >90% as determined by SDS-PAGE. 活性: Immobilized Biotinylated Human IL-21, Fc Tag (Catalog # IL1-H82F7) at 2 μg/mL (100 μL/well) can bind Human IL-21 R, His Tag (Catalog # ILR-H5226) with a linear range of 2-8 ng/mL (QC tested). 产品背景: Interleukin-21 (IL-21) is a secreted protein which belongs to the IL-15 / IL-21 family. Interleukin-21 / IL-21 belongs to a family of cytokines that bind to a composite receptor consisting of a private receptor (IL21R) and the common cytokine receptor gamma chain (gamma(C)). Interleukin-21 / IL-21 impacts a number of cell types, including CD8+ memory T cells, NK cells and subsets of CD4 memory T cells. The IL-21R is widely distributed on lympho-haematopoietic cells. IL-21 is a pleiotropic cytokine produced by CD4+ T cells in response to antigenic stimulation. Its action generally enhances antigen-specific responses of immune cells. IL-21 promotes the anti-tumor activity of CD8+ T-cells and NK cells. IL-21 exerts its effect through binding to a specific type I cytokine receptor, IL-21R, which also contains the γ chain (γc) found in other cytokine receptors including IL-2, IL-4, IL-7, IL-9 and IL-15. The IL-21/IL-21R interaction triggers a cascade of events which includes activation of the tyrosine kinases JAK1 and JAK3, followed by activation of the transcription factors STAT1 and STAT3. 产品描述: This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™). The protein has a calculated MW of 43.9 kDa. The protein migrates as 36 kDa and 48-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.SDS-PAGE 因为难以在供应系统上进行数据同步，所以了解更多产品规格及产品数据，请移步： http://www.acrobiosystems.cn/P1101-Biotinylated_Human_IL-21_Protein_Fc_Tag_Avi_Tag.html 订购方式 您可以通过官网查看产品信息、拨打订购电话、发送邮件或者直接点索取报价等方式进行订购，我们的客服将会竭诚为您服务。 电话：400-682-2521 网址：http://www.acrobiosystems.cn 邮箱：order.cn@acrobiosystems.com（订购及产品咨询）(请咨询时注明是在丁香通看到产品信息） 温馨提示：不可用于临床ZL。
