| 注意事项 | PA007389.m2a Syd Labs抗小鼠CD16/CD32(克隆2.4G2):用于流式细胞术、免疫组织化学(IHC)和免疫沉淀(IP)。它对FcγRII(CD32)和FcγRIII(CD16)具有高度特异性,并可减少背景染色;它可能不会阻断所有Fc受体。克隆X54-5/7.1是流式细胞术和功能检测中用于Fc阻断的最广泛的抗小鼠FcγRI(CD64)克隆。它可以阻止非特异性 Fc 受体与单核细胞、巨噬细胞和树突状细胞结合,提高抗体特异性。 |

重组 2.4G2 抗体可特异性结合小鼠 CD16(FcγIII)和 CD32(FcγII)受体蛋白。2.4G2 抗体是多种商业化 Fc 受体阻断剂(Fc block)的核心成分。由于大鼠、小鼠和人 IgG 的 Fc 片段均可结合小鼠 CD64(FcγI),因此重组 2.4G2 抗体广泛应用于流式细胞术(flow cytometry)、免疫组织化学(IHC)、免疫沉淀(IP)及阻断实验中,用以有效阻断 IgG 与小鼠 Fc 受体的非特异性结合。客户可根据具体实验应用需求选择不同的 IgG 同型(isotypes)。

“We found that signaling through the inhibitory Fc receptor FcγRIIB on T cells promotes apoptosis. … This pathway serves as a critical checkpoint to limit CD8+ T cell-mediated immunity. … Targeting this pathway with blocking antibodies like 2.4G2 can rescue T cells from apoptosis and enhance anti-tumor responses.”

“Neutralizing antibodies (nAbs) are key to preventing HIV infection, but their role in clearing cell-free virus from circulation is less clear. … Here, we show that cell-free HIV-1 opsonized with nAbs is rapidly cleared from the circulation via liver sinusoidal endothelial cells (LSECs). … This clearance and subsequent endocytosis are mediated by the inhibitory Fc receptor FcγRIIb, which can be blocked by anti-FcγRIIb antibodies.”

“Plasmacytoid dendritic cells (pDCs) are well known for their capacity to produce massive amounts of type I IFN. … In this study, we demonstrate that pDCs can efficiently take up immune complexes (ICs) via FcγRs. … This uptake of opsonized antigen leads to robust MHC class I and class II antigen presentation, inducing both CD4+ and CD8+ T cell activation in vivo.”

“Luciferase reporters are widely used to study gene regulation and promoter activity in bulk cell populations. … Here, we introduce LucFlow, a novel flow cytometry-based method to measure luciferase expression at the single-cell level. … This protocol utilizes specific Fc-blocking antibodies to eliminate background signal, allowing highly sensitive and precise quantification of reporter activity in heterogeneous cell mixtures.”

“Sphingosine-1-phosphate (S1P) is a bioactive lipid that regulates various physiological and pathological processes through five G protein-coupled receptors. … Using S1P2-deficient mice, we investigated the specific role of this receptor in IgE- and IgG-mediated systemic anaphylaxis. … Our results reveal that while S1P2 has minimal effect on the onset of anaphylaxis, it plays a prominent role in the recovery phase by regulating vascular permeability and cardiovascular function.”
