背景	B7 Homolog 4 (B7-H4) is glycosylated member of the B7 family of immune costimulatory proteins. Mature human B7-H4 consists of a 235 amino acid (aa) extracellular domain (ECD) with two Ig-like V-type domains, a 21 aa transmembrane segment, and a 2 aa cytoplasmic tail. It is widely expressed, including in kidney, liver, lung, pancreas, placenta, prostate, spleen, testis and thymus. B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. It also involved in promoting epithelial cell transformation.

> 95 % as determined by reducing SDS-PAGE.

Immobilized Anti-Human B7-H4 mAb at 2μg/ml (100 μl/well) can bind Biotinylated Human B7-H4-Fc-Avi. The ED50 of Biotinylated Human B7-H4-Fc-Avi is 0.23 ng/ml.

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。
