注意事项 PA007389.h1 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)。

1. Signaling through the inhibitory Fc receptor FcγRIIB induces CD8 T cell apoptosis to limit T cell immunity

Yao, et al. eLife. 2020 Jun 30;9:e54540. PMID: 32602844

“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.”

2. Accelerated clearance and degradation of cell free HIV by neutralizing antibodies occurs via FcγRIIb on liver sinusoidal endothelial cells by endocytosis

Ganesan, et al. PLoS Pathog. 2021 Mar 11;17(3):e1009367. PMID: 33690651

“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.”

3. Plasmacytoid Dendritic Cells Take Up Opsonized Antigen Leading to CD4+ and CD8+ T Cell Activation In Vivo

Bánki, et al. J Immunol. 2010 Jun 15;184(12):6607-15. PMID: 20483731

“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.”

4. LucFlow: A method to measure Luciferase reporter expression in single cells

Martinez, et al. PLoS One. 2023 Oct 4;18(10):e0292410. PMID: 37792610

“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.”

5. Interrogation of Sphingosine-1-phosphate receptor 2 function in vivo reveals a prominent role in the recovery from IgE and IgG-mediated anaphylaxis with minimal effect on its onset

Oskeritzian, et al. PLoS One. 2013 Mar 13;8(3):e58123. PMID: 23516456

“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.”
