一、基本信息

【性质简介】：In biological applications, solubility is one of the key factors affecting molecular activity ａnd stability. Propargyl PEG2 acid significantly enhances its solubility in biological systems by introducing hydrophilic PEG ligands, thereby ensuring its stability ａnd activity in complex biological environments. In addition, the design of the alkyne ａnd carboxyl ends of this crosslinking agent not only endows it with strong reaction ability, but also enables it to achieve diverse connections with other biomolecules. Especially in copper catalyzed click chemistry reactions, alkynes can quickly ａnd stably bind with azides, forming stable chemical bonds, further expanding their application scope in fields such as biomolecular modification ａnd biomaterial preparation.
