• intros：{"brand_intro":"博格隆（Bestchrom）是中国本土层析填料领域的领军企业，成立于2009年，总部位于上海。创始人张磊博士曾留学瑞典，师从层析技术先驱，回国后致力于打破Cytiva等外企的垄断。公司拥有自主知识产权的琼脂糖微球制备技术和Protein A配基偶联工艺，产品性价比极高。其Diamond系列填料在抗体纯化领域市占率已跃居国内前三，被多家头部生物药企纳入供应链。博格隆以\"让中国生物药企用得起好填料\"为使命，品控严格遵循ICH Q7标准。","product_intro":"Diamond Protein A是一款专为单克隆抗体（mAb）和Fc融合蛋白捕获而设计的高性能亲和填料。核心卖点在于其超高的动态结合载量（>60 mg mAb/mL填料）和极低的非特异性吸附。适用于抗体药物的工业化生产及临床前研究。与Cytiva MabSelect SuRe相比，其载量相当但价格低40%，且耐碱性更优（可耐受0.5M NaOH清洗）。特别适合预算有限但追求纯化效率的中小型生物技术公司。","key_specs":{"配基":"重组Protein A，耐碱性突变体，可耐受0.5M NaOH","动态结合载量":">60 mg 人IgG/mL 填料（保留时间4分钟）","基质":"高度交联琼脂糖，粒径75 μm","pH稳定性":"工作pH 3-10，清洗pH 2-12","最大流速":"200 cm/h，适配中低压层析系统","推荐应用":"单抗、双抗、Fc融合蛋白的捕获纯化"}}
