應用簡介:
芃碩生物(Ponsure)的*聚乙二醇羧基(LA-PEG-COOH)可以用來修飾蛋白質、多肽和其他帶有活性基團的材料。羧基(-COOH)可以很容易的和氨基形成穩定的酰胺鍵,也可以和羥基形成酯鍵。
LA:Lipoic acid, also known as thioctic acid, is an important bioactive molecule participating in various biological processes. PEG functionalized lipoic acid can be used to bind to metallic particle or film surface with its -S-S-bond. Lipoic acid group has high affinity to metallic surfaces and have been widely used for gold nanoparticles and quantum dots surfaces. PEGylated lipoic acid is water soluble and can be used directly in aqueous buffer.
