Thermo Scientific Pierce MT(PEG)4或甲基 -PEG4-硫醇是一种甲基和巯基封端化合物，含有 4-单元聚乙二醇 (PEG) 间隔，可用于修饰表面（如量子点、单层和磁粒子）。

MT(PEG)4 的特点：

•金属结合—末端单齿硫醇通过配位结合与金表面自发反应
• 甲基—末端甲基基团不具有反应性，该化合物的主要功能是包被量子点和其他表面以减少测定中的非特异性结合
• 聚乙二醇—PEG 基团具有灵活性、非免疫原性、亲水性，可显著减少蛋白质方法表面的非特异性结合
• 间隔臂—四单元 PEG 间隔使化合物长度接近 16 埃

MT(PEG)4 是一种单齿硫醇封端和甲基聚乙二醇化试剂。PEG 化合物具有确定的分子量和间隔长度，适用于修饰表面（如量子点、自组装单层和磁粒子）。使用聚乙二醇间隔（如该间隔）对固体表面进行功能化可显著减少非特异性蛋白结合。

在表面修饰中使用 MT(PEG) 4和 CT(PEG)12 可形成甲基醚封端的 PEG 和含周期暴露羧酸的 PEG 的亲水“苔”。暴露的羧酸基团可通过 EDC 和 sulfo-NHS 的碳二亚胺偶联反应偶联至亲和配体。

常见问题解答 (FAQ)

What are the recommended storage conditions for MT(PEG)4 Methyl-PEG-Thiol Compound (Cat. No. 26132)?

MT(PEG)4 Methyl-PEG-Thiol Compound (Cat. No. 26132) turns to liquid at RT. PEG-thiol reagents are low-melting solids that are difficult to weigh and dispense. To facilitate handling, make a stock solution by dissolving the entire contents of the bottle (100 mg in solid or liquid form) in dimethylsulfoxide (DMS) or dimethylformamide (DMF) to the desired stock concentration. Store unused stock solution at -20 degrees C.

Please note: the molecular weight of MT(PEG)4 Methyl-PEG-Thiol Compound is 224.32 g/ml.

For more information about protocol an use, please refer to the Instructions.

I received my order of MT(PEG)4 Methyl-PEG-Thiol Compound (Cat. No. 26132) as a liquid solution, instead of a solid form. Is this normal?

MT(PEG)4 Methyl-PEG-Thiol Compound (Cat. No. 26132) turns to liquid at RT. It is normal for the product to change state during transport as it is shipped at ambient temperature. The PEG-thiol reagents are low-melting solids that are difficult to weigh and dispense. To facilitate handling, make a stock solution by dissolving the entire contents of the bottle (100 mg in solid or liquid form) in dimethylsulfoxide (DMS) or dimethylformamide (DMF) to the desired stock concentration. Store unused stock solution at -20 degrees C.

Please note: the molecular weight of MT(PEG)4 Methyl-PEG-Thiol Compound is 224.32 g/ml.
