| 背景 |
CD39L1 protein (ENTPD2 or NTPDase2) is a member of the ecto-nucleoside triphosphate diphosphohydrolase family which the main role is termination of purinergic signaling. CD39L1 gene encodes a precursor protein with 495 amino acid residues which generates a 437 amino acid residues mature protein after processing. It is an ecto-nucleotidase that found on the surface of vascular adventitial cells and accessory vascular cells. CD39L1 is a Ca2+- and Mg2+-dependent enzyme that activates platelets by preferentially converting ATP to ADP. CD39L1 plays a role in regulating thrombosis and inflammation which is considered to be a therapeutic target for thromboregulation and the treatment of vascular inflammation. Alternative splicing of CD39L1 gene results in multiple transcript variants.

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。
