PA007201:体内实验级重组抗小鼠CD3e单克隆抗体(克隆号500A2),小鼠IgG2a Kappa

体内实验级重组抗小鼠CD3e单克隆抗体(克隆号500A2,小鼠IgG2a Kappa)是针对小鼠T细胞受体(TCR)复合物核心亚基CD3ε(CD3 epsilon)的序列明确(sequence-defined)重组单克隆抗体。CD3ε特异性表达于几乎所有成熟T细胞及胸腺细胞表面,作为TCR介导信号转导不可或缺的关键组件,在T细胞活化、增殖及免疫效应调控中发挥核心作用。该重组抗小鼠CD3e单克隆抗体(克隆号500A2)利用先进的哺乳动物细胞重组表达系统生产,完整保留了经典小鼠500A2克隆特异性结合CD3ε表位的高亲和力特性。相比极易发生基因漂移、内源轻链污染及批次间波动的传统杂交瘤表达试剂,重组表达技术彻底克服了这些质量缺陷,确保这款重组抗小鼠CD3e抗体具备极高的高纯度与批次间可重复性,为T细胞免疫学机制研究提供高可靠性的标准试剂。

在体内免疫学、肿瘤免疫治疗及自身免疫性疾病模型研究中,体内实验级重组抗小鼠CD3e单克隆抗体(克隆号500A2)被广泛应用于体内T细胞的特异性激活、功能调控或特定实验方案下的T细胞清除(In Vivo T Cell Depletion)。凭借小鼠IgG2a Kappa格式良好的分子稳定性与Fc段效应功能,该抗体能在体内模型中高效介导靶向免疫调节。为全面保障活体动物注射的安全性和实验数据的准确性,该低内毒素重组抗小鼠CD3e克隆500A2抗体经过严苛的多步纯化与质检,内毒素水平严格控制在超低标准(<1 EU/mg),且配方完全不含叠氮化钠与载体蛋白,有效避免了非特异性全身炎症反应,确保在肿瘤免疫微环境、移植排斥及T细胞功能评估中输出干净、符合顶级期刊发表标准的数据支持。

1. CD3e-immunotoxin spares CD62Llo Tregs and reshapes organ-specific T-cell composition by preferentially depleting CD3ehi T cells

Ren, X., et al. Front Immunol. 2022 Oct 27;13:1012674. PMID: 36389920

“Selective depletion of T cell subsets remains a major challenge in immunotherapy. This research illustrates that CD3e-targeted immunotoxins can precisely eliminate high-expressing CD3e T cells while leaving regulatory T cells (Tregs) with low CD62L expression unharmed. This targeted strategy provides a highly refined approach for modulating the immune landscape within specific organs.”

2. Comparison of CD3e Antibody and CD3e-sZAP Immunotoxin Treatment in Mice Identifies sZAP as the Main Driver of Vascular Leakage

Kim, S., et al. Toxins (Basel). 2022 Jun 15;14(6):410. PMID: 35740248

“Targeted therapies involving anti-CD3e antibodies and their derived immunotoxins are significant tools for T-cell disorder management. A common complication with these treatments is vascular leak syndrome, which presents safety concerns in clinical applications. This study confirms that the sZAP component of the immunotoxin, rather than the antibody moiety itself, is the primary mediator of vascular toxicity in mouse models.”

3. Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition)

Cossarizza, A., et al. Eur J Immunol. 2024 May;54(5):e50529. PMID: 38766904

“Flow cytometry is an essential technology for the analysis and isolation of immune cell populations. These guidelines offer comprehensive recommendations to ensure standardization and high-quality data generation across immunological research. This edition places particular emphasis on technical best practices for surface marker labeling and cellular sorting procedures.”

4. Cyclophosphamide depletes tumor infiltrating T regulatory cells and combined with anti-PD-1 therapy improves survival in murine neuroblastoma

Grier, J. M. P., et al. J Immunother Cancer. 2022 Sep;10(9):e004655. PMID: 36070923

“Regulatory T cells (Tregs) in the tumor microenvironment frequently inhibit effective anti-tumor immune responses. The authors demonstrate that cyclophosphamide treatment significantly reduces tumor-infiltrating Treg populations, thereby enhancing the efficacy of subsequent immune checkpoint blockade. The combination of chemotherapy and anti-PD-1 therapy leads to improved survival outcomes in a murine model of neuroblastoma.”

5. The adaptive immune system restrains Alzheimer’s disease pathogenesis by modulating microglial function

Marsh, S. E., et al. J Exp Med. 2016 Mar 7;213(3):363-75. PMID: 26903612

“The role of adaptive immunity in neurodegenerative conditions like Alzheimer’s disease has been a subject of intense investigation. This research demonstrates that the adaptive immune system plays a protective role by influencing the behavior and activation state of microglia. Modulation of this immune interaction offers a potential therapeutic avenue to restrain disease pathogenesis in the brain.”
