• intros：{"brand_intro":"Thermo Fisher Scientific 是全球科学服务领域的巨头，年营收超400亿美元。其Pierce品牌起源于20世纪70年代的蛋白质化学研究，2006年并入Thermo后成为蛋白质分析耗材的核心产品线。公司拥有全球最大的色谱质谱耗材生产基地，品控遵循六西格玛标准，每批次产品均通过质谱验证。创始人之一John B. Pierce是蛋白质交联技术的先驱。","product_intro":"Pierce 质谱级胰蛋白酶采用TPCK处理以去除胰凝乳蛋白酶活性，并通过HPLC纯化确保高纯度。核心卖点：即用型溶液（无需复溶）、低批间差异、兼容多种缓冲液（如50mM NH4HCO3）。适用于高通量蛋白质组学、生物制药表征。与Promega相比，其价格更低，但自溶峰略多，适合常规鉴定而非深度修饰组学。","key_specs":{"处理方式":"TPCK处理，抑制胰凝乳蛋白酶活性","纯度":"≥95%（HPLC）","浓度":"0.5 μg/μL 溶液","包装规格":"100 μg/支","储存条件":"-20℃保存，避免反复冻融","适用仪器":"所有主流质谱仪"}}
