  • 产品描述:

    Recombinant full-length human CCR8 protein was expressed by the intact DNA sequence of the human CCR8 in mammalian cells. This recombinant CCR8 protein was fused with a 10xHis-tag at the C-terminus. It contains less than 1.0 EU/ug determined by the LAL method. The CCR8 protein is biologically active as it can react with the mouse anti-6xHis monoclonal antibody and anti-CCR8 recombinant antibody, respectively. Its VLP-like structure was observed and confirmed by TEM. This recombinant CCR8 protein is highly immunogenic because it carries viral protein.

    Past studies have shown that the CCR8 protein is mainly expressed on monocytes, Th2 cells, and Treg cells. Many basic studies have also proved CCR8 plays an essential role in the biological processes of lymph node migration of monocyte-derived dendritic cells and Th2 cell-mediated type 2 inflammation. Researchers have found that CCR8 is a good biomarker of Treg cells at tumor sites and a potential tumor immune target. Subsequent studies found that the presence or absence of CCR8 does not affect the migration ability of Treg and its function in the tumor microenvironment. The development of CCR8-targeted monoclonal antibody drugs is expected to specifically inhibit the function of Treg at the tumor site and contribute to cancer treatment.

产品评价: CCR8多次跨膜,仅表达其胞外结构域会破坏其构象表位,造成部分抗原表位的丢失。华美生物公司表达全长蛋白,且具有较好的生物活性和免疫原性,对于我们后续开发抗体药物具有很大的帮助。赞赞赞

我注意到你提供了 CCR8 纳米圆盘,你能告诉我细胞内和细胞外结构域的暴露情况吗? 我们想筛选一组能够检测该靶标的细胞内或细胞外表位的抗体; 对于 VLP,根据定义,细胞内结构域没有暴露,并不适合我的实验。

VLP 只暴露胞外域 ,胞内域在包膜里面不暴露,主要就是筛识别胞外表位,所以VLP的可能不适合您的实验。 如果您想筛选一组能够检测该靶标的细胞内或细胞外表位的抗体,推荐:CSB-CF004847HU 是通过无细胞表达系统表达的蛋白全长,但是没有测活,不能保证识别内源样本,可以小规格订购尝试。或者您可以选择目的蛋白的胞内域或胞外域序列进行重组表达后,筛选识别靶标的细胞内或细胞外表位的抗体,但无法保证识别内源性样本。
