Single® 单B细胞抗体发现技术
借助SmocMab®小鼠免疫反应谱多样性、高抗体亲和力、低免疫原性等特征,SmocMab™全人源抗体开发平台可解决传统抗体开发周期长、免疫原性风险高、成功率不稳定等核心痛点,为药物研发机构提供全流程解决方案
我们提供高度灵活的阶段式合作模式,客户可在小鼠免疫后直接获取样本,亦可委托我们继续开展抗体发现,并进一步衔接体内药效检测。从免疫到药效验证,各环节均可独立切入或无缝串联,充分满足不同研发阶段与项目节奏的个性化需求。
专业技术团队针对您的定制需求进行个性化项目分析,沟通实施方案及原材料准备
根据前期与客户沟通的免疫方案进行小鼠免疫
多方位,多手段地进行抗体筛选优化,力求高效获得优质目的抗体
对获得的抗体进行多方位活性验证
借助自身庞大的疾病动物模型资源库,针对开发抗体进行体内药效实验
我们构建了多元化的抗体发现技术矩阵,涵盖杂交瘤、单B细胞及噬菌体文库三大路径。杂交瘤技术成熟稳定,单B细胞技术高通量快速,噬菌体文库则擅长广谱筛选,三者各有侧重、互为补充。可根据靶点特性与项目目标灵活选择最优方案,显著提升抗体发现成功率与效率。
依托庞大的动物模型资源库与丰富的临床前体内药效评价经验,我们提供从抗体发现到药效验证的一站式CRO服务。抗体发现完成后,无需跨平台衔接即可直接开展后续体内药效检测,大幅缩短研发周期,降低沟通与转移成本,实现高效闭环。
针对高同源性抗原的免疫难题而专门设计,可有效突破免疫耐受限制。凭借二十余年小鼠基因编辑经验,我们可针对不同靶点特性精准设计鼠源同源基因敲除方案,从源头消除自身识别干扰,使SmocMab®全人源抗体小鼠清晰识别人类靶点独特表位,激发更强、更特异的抗体应答,为高同源性困难靶点的抗体发现提供更优的精准免疫支撑。

High human–mouse homology across STEAP1 ECLs limits accessible epitopes
Immune tolerance limits STEAP1 responses in conventional immunization
KO strategy and proprietary immunogen design generate strong, target-specific titers

2,794 antibody sequences mapped across 650 clonotypes.
VH3/VH4 dominant immune response
Repertoire breadth/depth shown by CDR-H3 length distribution and V(D)J recombination patterns

Benchmark antibody: AMG509 (anti-steap1 IgG)
2,794 antibody sequences mapped across 650 clonotypes. Data represent a panel of 51 recombinant antibodies

Yellow and blue highlight: Internalization% range from 0.6- to 1.4-fold of AMG509 (anti-steap1 IgG)
Antibodies with different profiles can be used for different field : Internalizing for ADC while binding for TCE

High affinity binding with human PD-L1 comparable to Benchmark
High‑affinity human/cyno cross‑reactivity

Antibodies with high quality: 9/12 antibodies exhibit comparable interlization with BMK
Antibodies with high quality: 4/12 antibodies exhibit comparable blocking with BMK
BMK: Tecentriq-analogue

In vivo efficiency maily rely on blocking ability of antibodies.
Antibodies produced in SMOCmab mouse with high quality: Similar therapeutic effects with BMK without engineering modification of the V-region.
