Thermo Scientific Pierce Sulfo-SMCC No-Weigh 规格是一种水溶性胺对巯基交联剂,含有 NHS 酯和马来酰亚胺反应性基团,位于中等长度环己烷间隔臂(8.3 埃)的相对两端。

Sulfo-SMCC No-Weigh 规格的特点:

反应性基团sulfo-NHS 酯马来酰亚胺
可与以下基团发生反应:氨基和巯基基团
• 具有水溶性(与 SMCC 相比),因此可在生理溶液中进行交联
•高纯度结晶试剂可用于生成高纯度马来酰亚胺活化衍生物
• 环己烷桥可为马来酰亚胺基团提供额外稳定性,使 Sulfo-SMCC 成为马来酰亚胺活化蛋白的理想交联剂。马来酰亚胺基团在 4°C 下于 0.1 M 磷酸钠缓冲液(pH 值 7)中可保持稳定 64 小时。

磺基琥珀酰亚胺-4-(N-马来酰亚胺甲基)环己烷-1-羧酸盐 (Sulfo-SMCC) 是一种不可裂解和具有膜不可透过性的交联剂。它含有一个胺反应性 N-羟基琥珀酰亚胺(NHS 酯)和巯基反应性马来酰亚胺基团。NHS 酯在 pH 值 7-9 条件下与伯胺反应形成稳定的酰胺键。马来酰亚胺在 pH 值 6.5-7.5 条件下与巯基反应形成稳定的硫醚键。由于间隔臂中存在环己烷桥,Sulfo-SMCC 和 SMCC 的马来酰亚胺基团可在 pH 值高达 7.5 条件下保持稳定。因为它包含亲水磺酰基团,Sulfo-SMCC 在水和许多常用缓冲液中溶解多达 ∼10 mM,因此避免了使用可能会破坏蛋白结构的有机溶剂。

应用:
•抗体酶标记 - 酶和抗体特异性均可保留
• 通过一步或两步交联反应创建特异性生物偶联
•创建巯基反应性、马来酰亚胺活化载体蛋白,以用于偶联半抗原

规格:
按照最高规格生产 Sulfo-SMCC,以生产高特异性生物偶联物和马来酰亚胺活化蛋白,确保数据完整性并提供较高程度的交联一致性。每批 Sulfo-SMCC 都经过检测以符合以下最低质量标准。

• 鉴别:IR 扫描仅显示具有 Sulfo-SMCC 交联剂的结构和官能团特征的峰
•纯度:≥90%(通过 NMR 法定量,交联剂纯度的较高标准)
• 溶解度:≥10 mg/mL(溶于去离子水)

What is the shelf life of Sulfo-SMCC (Cat. No. 22322)?

Sulfo-SMCC is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended (desiccated at -20 degrees C). Please see section 8.1 of our Terms & Conditions of Sale (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/Terms-and-Conditions-of-Sale.pdf).

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.

We are using EDC to crosslink a protein onto carboxyl-modified beads. We would like to add in a linker molecule to extend the radius of beads to increase the surface area so more proteins can be immobilized. Is this possible?

To provide a linker between the beads and the target protein, you would need a molecule with a primary amine (to conjugate to the carboxyl group on the beads with EDC) on one end and another reactive group on the other (to conjugate to the protein). For instance, sulfo-SMCC (Cat. No. A39268) could be used in conjunction with PDPH (Cat. No. 22301):
The method is outlined below:
1. Conjugate the target protein to the NHS ester (amine-reactive) group of Sulfo-SMCC. This will produce a maleimide-activated target protein via its primary amines (lysines and N-terminus).
2. Remove the excess sulfo-SMCC by desalting or dialysis.
3. React the maleimide-activated target protein to PDPH via sulfhydryls. (Lysines and N-terminus now are connected to hydrazide (amine) group with an extended linker)
4. Remove excess PDPH by desalting or dialysis.
5. React the hydrazide-activated target protein with carboxyl beads in the presence of EDC.
6. Use appropriate buffer to rinse off excess target protein from the carboxyl beads.
