运输条件	This product is provided as lyophilized powder which is shipped with ice packs.
制剂	Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual.
复溶方法	Please refer to the printed manual for detailed information.
背景	Interleukin-17 is a potent pro-inflammatory cytokine produced by activated memory T cells. There are at least six members of the IL-17 family in humans and in mice. As IL-17 shares properties with IL-1 and TNF-alpha, it may induce joint inflammation and bone and cartilage destruction. This cytokine is found in synovial fluids of patients with rheumatoid arthritis, and produced by rheumatoid arthritis synovium. It increases IL-6 production, induces collagen degradation and decreases collagen synthesis by synovium and cartilage and proteoglycan synthesis in cartilage. IL-17 is also able to increase bone destruction and reduce its formation. Blocking of interleukin-17 with specific inhibitors provides a protective inhibition of cartilage and bone degradation.

Immobilized Cynomolgus IL-17A-His (Cat#PKSQ050109) at 10 μg/ml (100 μl/well) can bind Anti-Human IL-17A mAb. The ED50 of Anti-Human IL-17A mAb is 128 ng/ml.

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: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。

Q6: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。
