背景 |
Delta-like protein 1 (DLL1) is a type I transmembrane protein that belongs to the Delta/Serrate/Lag2 (DSL) family of Notch ligands. Mature human DLL1 consists of a 528 amino acid (aa) extracellular domain (ECD) with one DSL domain and eight EGF-like repeats, a 23 aa transmembrane segment, and a 155 aa cytoplasmic domain. Within the ECD, human DLL1 shares 91% aa sequence identity with mouse and rat DLL1. The residual membranebound portion of DLL1 can be cleave by presenilin-dependent γ-secretase, enabling the cytoplasmic domain to migrate to the nucleus. DLL1 localizes to adherens junctions on neuronal processes through its association with the scaffolding protein MAGI1. DLL1 is widely expressed, and it plays an important role in embryonic somite formation, cochlear hair cell differentiation, plus B and T lymphocyte differentiation. The upregulation of DLL1 in arterial endothelial cells following injury or angiogenic stimulation is central to postnatal arteriogenesis. DLL1 is also overexpressed in cervical carcinoma and glioma and contributes to tumor progression.

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。
