Thermo Scientific Pierce Sulfo-NHS是一款用于将羧基转换为氨基反应性NHS酯的化学修饰试剂,适用于生物偶联、交联、标记和固定等操作。

Sulfo-NHS的特点:

• Sulfo-NHS提高EDC介导的偶联效率
• 能够利用任何含羧基分子形成氨基反应性NHS酯或Sulfo-NHS酯
• Sulfo-NHS衍生物通常直接溶于水(可直接加入生理缓冲液中),不可穿透细胞膜(可用于标记细胞表面)
• 高纯度的晶体Sulfo-NHS可用于生成高品质活化衍生物

Sulfo-NHS(N-羟基琥珀酰亚胺)能够控制和修饰碳二亚胺交联反应,包括活化羧酸根(—COOH)以偶联伯胺基(—NH2)。通过将Sulfo-NHS与一种含羧基分子及一种脱水试剂(如碳二亚胺EDC(EDAC))混合,可以方便地合成相关衍生物。该方法是制备许多类型蛋白标记试剂的基础,包括氨基反应性荧光染料、生物素亲和标签和聚乙二醇化化合物。

应用:
• 提高EDC偶联反应效率
• 将羧基转化为氨基反应性Sulfo-NHS酯
• 在蛋白与羧基包被微珠或表面之间实现高效交联
• 使用氨基反应性Sulfo-NHS酯活化纳米颗粒

Sulfo-NHS的规格:
我们按照最高标准生产N-羟基琥珀酰亚胺以获得最特异的生物偶联物,进而确保数据的完整性,并为您提供最高水平的实验一致性。每一批次的Sulfo-NHS均经过测试,符合以下标准:

纯度—定量NMR检测纯度≥95%(交联剂纯度的最高标准)
每批次的平均纯度高于99%
可溶性—2 mg/mL下溶解于去离子水,形成清澈的无色溶液
鉴别检测—IR扫描只显示N-羟基琥珀酰亚胺的特性峰值

How does a product with "No-Weigh" format reduce my concern over reagent stability?

The No-Weigh product format, where small amounts of reagent are pre-weighed and packaged separately, prevents the contamination and loss of reagent reactivity over time associated with repetitive opening and closing of a single vial. This format enables use of a fresh vial of reagent each time and eliminates the hassle of weighing out small amounts of reagent. Please view additional information and the video at: https://www.thermofisher.com/us/en/home/life-science/protein-biology/protein-labeling-crosslinking/no-weigh-packaging.html
