| 背景 |
Macrophage galactose N-acetyl-galactosamine-specific lectin 2(Mgl2), also known as CD301b, is a 38 kDa member that belongs to the C-type lectin family. Two MGL proteins are encoded by separate genes in the mouse, but share 91% amino acid (aa) identity in the extracellular domain (ECD). Only one MGL occurs in human and rat and this MGL is structurally more similar to mouse MGL1 than MGL2. However, human MGL and mouse MGL2 both bind specifically to terminal GalNAc residues, in contrast with mouse MGL1 which binds Lewis X. GalNAc recognition is likely to be important in dendritic cell-mediated tolerance to self-gangliosides as well as recognition of tumor antigens and parasite glycoproteins.

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。
