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. BCN group readily reacts with azide-tagged biomolecules to form 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.
