產(chǎn)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.

■ 常見問題解答

我注意到你提供了 CCR8 納米圓盤，你能告訴我細(xì)胞內(nèi)和細(xì)胞外結(jié)構(gòu)域的暴露情況嗎？我們想篩選一組能夠檢測(cè)該靶標(biāo)的細(xì)胞內(nèi)或細(xì)胞外表位的抗體；對(duì)于 VLP，根據(jù)定義，細(xì)胞內(nèi)結(jié)構(gòu)域沒有暴露，并不適合我的實(shí)驗(yàn)。

VLP 只暴露胞外域，胞內(nèi)域在包膜里面不暴露，主要就是篩識(shí)別胞外表位，所以VLP的可能不適合您的實(shí)驗(yàn)。如果您想篩選一組能夠檢測(cè)該靶標(biāo)的細(xì)胞內(nèi)或細(xì)胞外表位的抗體，推薦：CSB-CF004847HU 是通過無(wú)細(xì)胞表達(dá)系統(tǒng)表達(dá)的蛋白全長(zhǎng)，但是沒有測(cè)活，不能保證識(shí)別內(nèi)源樣本，可以小規(guī)格訂購(gòu)嘗試。或者您可以選擇目的蛋白的胞內(nèi)域或胞外域序列進(jìn)行重組表達(dá)后，篩選識(shí)別靶標(biāo)的細(xì)胞內(nèi)或細(xì)胞外表位的抗體，但無(wú)法保證識(shí)別內(nèi)源性樣本。
