背景 |
IL-23 , which is mainly secreted by antigen-presenting cells , is a member of the IL-12 family , which includes IL-12 , IL-27 , and IL-35. IL-23 is a heterodimeric cytokine , comprised of a unique p19 subunit and p4 subunit , the latter of which is shared with IL-12. The receptor for IL-23 consists of IL-23R and IL-12Rβ1 , the latter of which is also characteristic of IL-12. IL-23 is essential for Th17 differentiation , expansion , and survival by binding to its receptor , thereby activating the signaling pathway. Many studies revealed that the IL-23/Th17 pathway is implicated in the pathophysiology of various autoimmune diseases , such as autoimmune arthritis , primary biliary cirrhosis , and inflammatory bowel disease.

Q1:重组蛋白有活性吗?可以做活性检测吗?
活性说明的见说明书bio-activity部分;如果说明书显示没有生物活性或则显示生物活性检测中,则说明这个蛋白没有生物活性数据,需要客户自己检测。
Q2:重组蛋白是否测序验证过?
在售重组蛋白默认不做测序分析/验证。
Q3:蛋白的运输条件是什么?
我们的蛋白有液体和冻干粉2种形式,一般来说冻干粉可以用冰袋、蓝冰、干冰运输;液体可以用蓝冰或干冰运输。
Q4:蛋白是通过什么方式纯化的?
一般通过纯化标签进行亲和纯化,常规有镍柱/His Tag、protein AG/Fc tag、标签抗体凝胶等。
Q5:蛋白可以用于细胞培养/注射小鼠吗?
内毒素含量小于0.1 ng/μg (1 EU/μg)的蛋白都可以用于细胞培养/注射小鼠。
Q6:蛋白发货形式可以是冻干粉吗?可以发液体吗?
默认按照说明书标注的形式发货;如果有特殊需求,需要根据蛋白情况确定。原则上,冻干粉蛋白可以发液体形式,液体蛋白不能发冻干粉形式。
Q7:蛋白Buffer里是否含有denaturants(变性剂)?
我们在售重组蛋白一般不含变性剂,具体见说明书的formulation信息。常见变性剂有:尿素和盐酸胍。
Q8:无标签蛋白纯化方式?
蛋白的纯化方式一般通过标签进行亲和纯化,无标签的蛋白是在纯化后进行了标签切除。
Q9:AF蛋白可以提供吗?
在售的重组蛋白都属于Animal component free protein。在售重组蛋白里不含任何直接来源与动物和人的制品:比如血清,血浆,全血,BSA,OVA等。
