4 arm PEG SH，2k,3.4k,5k,10k,20k,40k,四臂PEG巰基，四臂聚乙二醇巰基

產(chǎn)品簡介：

      巰基官能化PEG（4ARM-PEG-SH）可以用來修飾蛋白質(zhì)、多肽以及其它材料或者小分子。馬來酰亞胺和巰基在PH6.5-7.5很容易形成穩(wěn)定的硫醚鍵。硫醇基團對金表面具有很高的親和性，廣泛用于金納米粒子或金膜修飾。PEG修飾可提高溶解度和穩(wěn)定性，減少蛋白質(zhì)和肽的免疫原性。它也能抑制帶電分子在修飾表面的非特異性結(jié)合。  

結(jié)構(gòu)式：

物理性質(zhì)：

狀    態(tài)：固體或者粘稠液體，取決于分子量大小。

溶 解 性：溶于大部分有機溶劑，溶于水。

保持條件：-20℃長期保存，避光，干燥。

注意事項：取用一定要干燥，避免頻繁的溶解和凍干。
