• intros：{"brand_intro":"诺唯赞是中国领先的分子生物学酶与试剂盒供应商，成立于2012年，总部位于南京。公司以'酶工程'为核心技术，拥有自主知识产权的DNA聚合酶、逆转录酶等。在ChIP领域，其试剂盒采用专利的'超低背景'磁珠技术，并配套优化的超声缓冲液，显著提高染色质片段化效率。品控遵循ISO 9001体系，每批次产品均经过NGS验证。创始人曹林博士是酶工程专家，曾获国家科技进步奖。","product_intro":"该试剂盒专为ChIP-seq设计，核心卖点是高灵敏度和低起始细胞量（最低可至1×10^5个细胞）。其磁珠表面经过特殊钝化处理，非特异性结合率低于0.05%。与赛默飞Pierce相比，其配套的超声缓冲液能减少DNA降解，提高片段化均一性。适用场景包括稀有细胞样本（如干细胞、原代细胞）的ChIP-seq和ChIP-qPCR。竞品对比优势在于其DNA回收效率高，洗脱后无需纯化即可直接建库。","key_specs":{"磁珠类型":"超低背景磁珠，粒径0.5μm，表面钝化处理","样本容量":"每次反应可处理1×10^5至1×10^6个细胞","抗体兼容性":"兼容小鼠、兔、山羊IgG，无需预吸附","洗脱体积":"最终DNA洗脱体积为20μL，适合低起始量样本","储存条件":"2-8°C冷藏保存，有效期12个月","配套试剂":"包含蛋白酶K、RNase A、超声缓冲液及DNA纯化柱"}}
