维百奥生物代理Quartett品牌
Quartett公司于1986年在德国柏林创立，始终致力于癌症防治领域并推动肿瘤诊断技术革新。quartett专注于两大核心业务：为解剖病理学/免疫组化（IHC）领域生产单克隆抗体，同时为制药工业及科研机构提供合成多肽产品。
▍Quartett两大核心技术
● 兔源重组单克隆抗体技术平台：突破传统鼠源抗体的局限。相较于鼠类免疫系统，兔源免疫系统具有显著优势——可识别更微小表位（≤5个氨基酸）、产生亲和力达10⁻¹²M的高特异性抗体，这使得quartett公司开发的诊断试剂在癌症检测中展现出卓越性能（如PD-L1检测灵敏度92.7%）。
● 合成肽制备技术：专业生产HPLC纯度＞95%的定制肽，包括蛋白酶抑制剂及抗体生产用免疫原肽。该平台的成功更直接推动了兔源重组抗体技术的突破性发展，形成从合成肽到高价值诊断抗体的完整技术闭环。所有试剂均优化适配全自动染色平台（如Roche Ventana/Leica BOND）及人工染色流程。
