• intros：{"brand_intro":"Thermo Scientific是赛默飞世尔科技旗下核心品牌，全球科研服务行业巨头，年营收超400亿美元。其多聚甲醛产品以'无甲醇'（Methanol-free）配方闻名，专为流式细胞术和单细胞测序设计。品牌拥有百年历史，从热电公司起家，现覆盖从试剂到仪器的全产业链。品控理念是'零缺陷'，每瓶产品附带电子追溯码，可查询生产全流程数据。","product_intro":"该产品为16%高浓度多聚甲醛溶液，不含甲醇稳定剂，避免甲醇对细胞表面抗原的破坏。核心卖点：高浓度（16%）便于用户自行稀释至所需浓度（如4%），且无甲醇配方确保流式抗体染色不受干扰。与Sigma粉末相比，即用型液体更安全；与碧云天相比，浓度更高、纯度更优。适用场景：流式细胞术固定/破膜、单细胞RNA测序样本固定、活细胞成像前的快速固定。","key_specs":{"浓度":"16% (w/v) 多聚甲醛","甲醇含量":"未检出 (HPLC)","包装":"100ml/瓶","储存条件":"室温 (15-30℃)","适用仪器":"流式细胞仪、单细胞测序平台","保质期":"24个月"}}
