抗体发现

A scientist wearing a face mask, safety goggles, and blue gloves is holding a conical flask with an orange cap. The flask contains a pink liquid and some solid particles. In the blurred background of the laboratory, bioanalytical development tools hint at advanced research in absolute bioavailability.

康龙化成抗体发现平台,可为客户提供包括新型和高效单克隆抗体的发现、抗体工程以及抗体表征等服务。我们已成功运用噬菌体展示和杂交瘤两大技术平台,助力新型抗体药物和试剂的研发。

在鼠抗体人源化方面,我们团队拥有丰富的实操经验。该过程旨在保留亲本抗体的结合亲和力和特异性,同时消除异源抗体在患者体内可能引发的免疫原性。此外,我们建立了多种生物物理、生化及细胞检测分析方法,为抗体理化性质和生物活性的表征评估奠定了坚实基础。
