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. Azide moiety is widely tolerated in biological systems with minimal inteference to their activities. It readily reacts with alkyne-labeled biomolecules via click chemistry. They have been widely used in target drug delivery and MRI imaging applications.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.
