Product introduction
与包含不同 PEG 链长的非均匀混合物的典型 PEG 试剂相比,该 PEG 试剂是具有确定的分子量和间隔臂长的均质化合物,在优化和表征交联应用方面提供了更高的精度。 含有 N-羟基琥珀酰亚胺(NHS) 酯的同型双功能交联剂通常用于蛋白质结构的低分辨率 3-D 研究和蛋白质相互作用分析。 特点和优势: · 反应基:NHS 酯(两端) · 反应性:氨基(伯胺) · 在 pH 7-9 下,NHS 酯与 -NH2 基反应形成稳定的酰胺键 · 水溶性;与非聚乙二醇化的 Bs3(也可溶)和 DSS(不溶于水)进行比较 · 不可透过膜,允许细胞表面标记 · 通过柔性PEG间隔臂不可逆地交联蛋白质或肽 · 聚乙二醇间隔臂有助于保持偶联物溶解度 · 有确定结构和分子量的纯化合物,确保可重复的蛋白质修饰效果 · PEG间隔臂提供独特的优势,包括增加稳定性、降低聚集倾向和降低免疫原性 · 非常适合小分子或肽结合 Bis-PEG5-NHS ester is a PEG derivative containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Features and Benefits · Reactive groups: NHS ester (both ends) · Reactive towards: amino groups (primary amines) · NHS esters react with—NH2 groups at pH 7-9, forming stable amide bonds · Water-soluble; compare to non-pegylated BS3 (also soluble) and DSS (water-insoluble) · Membrane-impermeable, allowing for cell surface labeling · Irreversibly crosslink proteins or peptides by flexible PEG spacer arms · Polyethylene glycol spacer arms help maintain conjugate solubility · Pure compound with defined structure and molecular weight, ensuring reproducible protein-modification effects · PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity · Ideal for small molecule or peptide conjugations
