B7-H3/CD276重组蛋白、抗体及稳转细胞株
B7-H3，又称CD276，是B7家族的重要免疫调节膜蛋白。B7-H3在部分正常组织中的基础表达相对有限，但在多种实体瘤及肿瘤相关基质、血管或免疫细胞中可出现较高表达，并与肿瘤进展、侵袭及免疫微环境调控等过程相关。虽然其生理受体及完整免疫调节机制仍在持续研究中，但B7-H3良好的细胞表面可及性和肿瘤相关表达特征，使其成为抗体、ADC、双/多特异性抗体以及细胞治疗领域广泛关注的靶点。针对不同治疗形式，研究者通常需要评价抗体对不同胞外结构区域的识别、细胞表面结合、跨物种反应性，以及候选分子的内吞或细胞功能特性。
缔码生物提供人源B7-H3完整及不同胞外区域ECD重组蛋白、猴源B7-H3蛋白、兔单克隆抗体、Biosimilar参照抗体、PE/生物素标记抗体以及B7-H3过表达K562稳转细胞株。不同胞外域的片段蛋白可用于ELISA、抗体筛选、表位定位和结构域识别；人猴蛋白组合可支持跨种属反应性评价；流式验证抗体和PE偶联抗体可用于细胞表面B7-H3检测；稳转细胞株则适用于FACS、Cell Binding和候选抗体筛选。相关资源还可进一步衔接内吞、ADC或细胞功能评价，为B7-H3靶向分子的早期开发提供完整工具链。
