产品是一种硫醇化的羧基聚乙烯。4α;-巯基-ω 羧基 PEG(HS-PEG-COOH)异双功能 PEG,其功能性端基的具有非常不同的反应性。HS-PEG-COOH 抑制与活细胞的非特异性结合。
应用
HS-PEG-COOH 可能会在表皮生长因子(EGF)共轭的表面增强拉曼光谱(SERS)纳米粒子的制造过程中被连接到金纳米粒子末端。HS-PEG-COOH 可涂覆到绝缘体上硅光子生物传感器芯片上。量子点(QD)/病毒样颗粒(VLP)只能从 HS-PEG-COOH 涂覆到 QD 上获得。它可用于稳定纳米粒子并防止其聚集。应用可能包括:生物偶联、药物递送、PEG 水凝胶、交联剂和表面功能化
Product is a thiolated carboxylic-polyethylene . 4α;-sulfanyl—ω carboxy PEG (HS–PEG–COOH) heterobifunctional PEGs with functional end-groups of very different reactivity. HS-PEG-COOH inhibits nonspecific binding to living cells.HS-PEG-COOH may be tethered to the gold nanoparticle end during the fabrication of epidermal growth factor (EGF)-conjugated surface-enhanced Raman spectroscopy (SERS) nanoparticles. HS-PEG-COOH was coated onto silicon-on-insulator photonic biosensor chips. Quantum dots (QD)/ virus-like particles (VLPs) could be obtained only from HS-PEG-COOH-coated QDs. It may be used to stabilize nanoparticles and prevent its aggregation.Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
