Molecular Diagnostics
PEGylation Building Blocks for Advanced Diagnostic Platforms
Polyethylene glycol (PEG) plays a critical role in modern diagnostic technologies by improving the stability, biocompatibility, and targeting efficiency of imaging probes and detection systems. Through precise control of molecular weight and functional end groups, PEG enables the development of highly reproducible diagnostic platforms for fluorescence imaging, MRI, nanoparticle tracking, and biosensing applications.

| Targeted Diagnostic Platforms | Heterobifunctional PEG Linkers; Clickable PEGs | Site-specific ligand conjugation; Enhanced targeting accuracy |
| Nanoparticle Imaging Systems | DSPE-PEG; DMG-PEG; PEG-Lipid Conjugates | Stabilize nanoparticles; Prolong circulation time |
| Biosensors & Detection Assays | Biotin-PEG; NHS-PEG Reagents | High-affinity capture; Reduced non-specific binding |
Imaging Probe Stabilization with PEG
PEGylation significantly improves the performance of diagnostic probes by increasing aqueous stability and minimizing non-specific interactions in biological environments. mPEG-modified nanoparticles, liposomes, and fluorescent probes exhibit prolonged circulation and enhanced signal consistency in vivo.
Key products: mPEG, mPEG-NHS, mPEG-SH, DSPE-PEG, DMG-PEG
Targeted Diagnostic & Molecular Imaging Systems
Functionalized PEG reagents enable precise conjugation of targeting ligands, antibodies, peptides, and imaging agents to diagnostic nanomaterials. PEG-COOH and heterobifunctional PEG linkers support efficient covalent coupling for tumor-targeted imaging and site-specific probe construction.
Key products: PEG-COOH, NHS-PEG-Maleimide, Azide-PEG, DBCO-PEG, PEG-NHâ‚‚
PEG-Lipid Platforms for Nanodiagnostics
PEG-lipid conjugates are widely used in nanoparticle-based diagnostic systems, including liposomal imaging agents, quantum dots, and magnetic nanoparticles. The PEG corona enhances colloidal stability and biocompatibility, while the lipid domain supports membrane integration and payload encapsulation.
Key products: DSPE-PEG, DMG-PEG, PEGylated Lipids, Heterobifunctional PEG-Lipids
Biosensors & Affinity-Based Detection
PEGylated affinity reagents reduce background interference and improve assay sensitivity in biosensors and diagnostic devices. Biotin-functionalized PEG reagents enable strong and selective streptavidin-based capture while minimizing non-specific adsorption.
Key products: Biotin-PEG-NHS, NHS-PEG-Biotin, PEG-Biotin, Clickable PEG Reagents
