| 背景 |
Interleukin 23 (IL-23) is a heterodimeric cytokine composed of two disulfide-linked subunits, a p19 subunit that is unique to IL-23, and a p40 subunit that is shared with IL-12. The p19 subunit has homology to the p35 subunit of IL-12, as well as to other single chain cytokines such as IL-6 and IL-11. The p40 subunit is homologous to the extracellular domains of the hematopoietic cytokine receptors. Although p19 is expressed by activated macrophages, dendritic cells, T cells, and endothelial cells, only activated macrophages and dendritic cells express p40 concurrently to produce IL-23. IL-23 has biological activities that are similar to, but distinct from IL-12. Both IL-12 and IL-23 induce proliferation and IFN-gamma production by human T cells. While IL-12 acts on both naive and memory human T cells, the effects of IL-23 is restricted to memory T cells.

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: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。
Q3: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。
Q4: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。
Q5: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。
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。
