背景 |
Herpesvirus entry mediator (HVEM) is a type I membrane protein in the TNF receptor superfamily; and it can both promote and inhibit T cell activity. HVEM is highly expressed on na?ve CD4+ T cells; CD8+ T memory cells; regulatory T cells; dendritic cells; monocytes; and neutrophils. It functions as a receptor for BTLA; CD160; LIGHT/TNFSF14; and Lymphotoxin-alpha. Ligation of HVEM by LIGHT triggers T cell; monocyte; and neutrophil activation and contributes to Th1 inflammation and cardiac allograft rejection. In contrast; HVEM binding to CD160 or BTLA suppresses T cell and dendritic cell activation and dampens intestinal inflammation. HVEM enhances the development of CD8+ T cell memory and Treg function. It is additionally expressed on intestinal epithelial cells; where its binding by intraepithelial lymphocyte (IEL) expressed CD160 promotes epitheilal integrity and host defense. The herpesvirus envelope glycoprotein gD; which binds HVEM to initiate membrane fusion; can antagonize both BTLA and LIGHT binding.

Q1: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。
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: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。
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。
