• intros：{"brand_intro":"樱花（SAKURA）是日本知名的病理学与实验室设备品牌，隶属于樱花精机株式会社（Sakura Finetek Japan），成立于1918年。公司以\"精准病理，守护生命\"为使命，在组织包埋、染色和切片领域拥有多项核心技术。Tissue-Tek系列是其旗舰产品线，O.C.T.（Optimal Cutting Temperature）包埋剂专为冷冻切片设计，全球市场占有率超过40%。樱花坚持日本本土制造，品控严格，每批次均通过细胞毒性测试。创始人樱井精一（Seiichi Sakurai）最初以制造显微镜起家，后转型病理耗材，其\"匠人精神\"贯穿产品研发。","product_intro":"Tissue-Tek O.C.T.是冷冻切片领域的标杆产品，定位高端免疫组化和分子病理学。核心卖点是极低熔点（-10°C至-20°C），专为冷冻切片机（如徕卡CM1950）优化，能快速冷冻并保持组织形态。适用于术中冰冻诊断、荧光原位杂交（FISH）和酶组织化学实验。与徕卡PEG 300相比，O.C.T.更适合冷冻而非石蜡包埋，其粘度低、渗透快，切片厚度可薄至1微米。竞品（如赛默飞Cryo-Gel）在低温韧性上略逊一筹。用户评价其\"冷冻切片首选，无替代品\"。","key_specs":{"主要成分":"聚乙烯醇（PVA）和聚乙二醇（PEG）混合物","熔点范围":"-10°C至-20°C","切片厚度":"1-5微米（推荐）","适用温度":"-20°C至-30°C（冷冻切片机）","包装规格":"125ml/瓶","保质期":"36个月（-20°C保存）"}}
