Folate PEG linker serves as an excellent target oriented molecular probe. Folic acid PEG linkers have improved aqueous solubility compared to their non-PEG versions. They have been widely used in target drug delivery and MRI imaging applications. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The PEG spacer increase the solubility of the resulting complex in aqueous media.
Axispharm offers 3000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
