• intros：{"brand_intro":"纽英伦生物技术（New England Biolabs，简称NEB）成立于1974年，总部位于美国马萨诸塞州伊普斯威奇，是全球限制性内切酶和分子生物学试剂的先驱。公司以\"科学家服务科学家\"为理念，创始人Donald G. Comb博士是限制性内切酶发现者之一。NEB在RNA酶抑制剂领域深耕20余年，Murine系列采用鼠源重组蛋白，具有高亲和力和低免疫原性。品牌以严格的质控和环保生产著称，所有产品均通过ISO 9001认证，在中国市场拥有大量忠实用户，尤其受高校实验室青睐。","product_intro":"Murine RNase Inhibitor是NEB推出的高性价比RNA酶抑制剂，定位中端市场，适合日常RNA操作。核心卖点在于其鼠源蛋白对RNase A的抑制常数（Ki）低至10^-10 M，且与逆转录酶兼容性极佳。适用于cDNA合成、体外转录和RNA稳定性实验。相比赛默飞RiboLock，Murine在成本上降低约30%，但热稳定性稍弱（45°C以上活性下降明显）。产品提供40 U/μL浓度，包装灵活，从400 U到4000 U可选，适合不同规模实验室。","key_specs":{"抑制活性":"≥40 U/μL，可抑制4 ng RNase A","纯度":"≥99%（HPLC检测）","热稳定性":"45°C孵育30分钟后残留活性≥80%","储存条件":"-20°C，可短期4°C存放","适配实验":"cDNA合成、体外转录、RNA保护","包装规格":"400 U/支（M0314S），另有2000 U/支（M0314L）"}}
