研究方向

IFN-lambda 2 (IL-28A) 是 III 型干扰素家族的成员。人 IFN-lambda 2 与小鼠 IFN-lambda 2 有 65.1% 的共同氨基酸同一性。IFN-lambda 2 特别是在病毒或细菌感染后由树突状细胞 (DC) 产生。
IFN-lambda 2 通过包含 IFNλ 受体 1 (IFNLR1) 和 IL-10 受体亚基-β (IL-10RB) 的异二聚体受体复合物介导作用。当与受体复合物结合时,Jak1和Tyk2将被激活,并导致IFN-λR1(胞内结构域,Tyr406和Tyr343,Tyr517)的酪氨酸磷酸化,并激活STAT1和STAT2。激活的 STAT1 和 STAT2 与 IRF-9 (p48) 一起形成三聚体转录因子复合物 (ISGF3)。形成的 ISGF3 复合物随后易位至细胞核并促进 IFN 刺激基因 (ISG) 的产生,例如 IRF7、MX1 和 OAS1。
IFN-lambda 2 具有抗病毒、抗肿瘤和免疫调节活性。据报道,IFN-lambda 2 可调节 CD11c+ DC 细胞功能并促进 Th1 分化,从而抑制过敏性气道疾病。

描述
Recombinant Human IFN-lambda 2/IL-28A Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val26-Val200) of human IL-28A/IL28A (Accession #NP_742150.1) fused with a 6×His tag at the C-terminus.
储存
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月;
复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。
复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。

背景信息

IL 28A (Interferon-lambda 2; IFN-lambda 2), IL-28B/IFN-lambda 3, and IL-29/IFN-lambda 1 are type III interferons which are distantly related to IL-10 family and type I IFN family cytokines . IL 28A ,interleukin 28B (IL28B), and interleukin 29 (IL29) are three closely related cytokine which are expression can be induced by viral infection.In the liver, the IL-28A induced Th1 cytokine response contributes to inflammation in T cell mediated hepatitis. IL-28A additionally exhibits anti-tumor activity, in part by enhancing IL-12 dependent anti-tumor CTL responses in vivo . In contrast, it is up-regulated in invasive bladder cancer where it promotes tumor cell migration.
