| 背景 |
Mitofusin 2 (MFN2) is a GTPase dynamin-like protein of the outer mitochondrial membrane, encoded in the nuclear genome by the MFN2 gene located on the short (p) arm of chromosome 1. MFN2 is an important transmembrane GTPase in the mitochondrial outer membrane and it can block cells in the G0/G1 stage of the cell cycle. MFN2 protein is involved in several intracellular pathways but is mainly involved in a network that has an essential role in several mitochondrial functions, including fusion, axonal transport, interorganellar communication, and mitophagy. Mitofusin 2 (Mfn2) is a key protein in mitochondrial fusion and it participates in the bridging of mitochondria to the endoplasmic reticulum (ER). Recent data indicate that Mfn2 ablation leads to ER stress. Mitofusin-2 (MFN2) deficiency in trophoblastic cells is an important cause for early miscarriage. MFN2 can regulate mitochondrial autophagy. Several reports show that MFN2 is a target of different miRNAs.

Q1: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。
Q2: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。
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。
Q5: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。
Q6: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。
Q7: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。
