CD Bioparticles’ products with customized delivery strategies, precise designs and modifications of drugs or drug-contained cargos, and advanced technical platforms can help you to solve:
The challenges you might meet:
- Strong immune response or foreign body response of your materials
- Fibrosis and fibrous encapsulation of your drug delivery materials
- Fast clearance of your drug cargos
- Limited PEGylation methods on your materials
Key Features
- Lipid PEGs
- Diversified functional groups for various applications; Enhanced lipophilic properties for small and macromolecule formulations; Customized size and functionalities
- Y-Shaped PEGs
- The sterically bulky structure of Y-shape branched PEG derivatives, consisting of two linear methoxy PEG chains attached to a central core with an active NHS group, may help to reduce the number of attachment sites to a protein molecule and enable simple and efficient modification of proteins and other biological agents that contain lysines.
- Trifunctional PEGs
- Designed as linkers for Antibody-Drug Conjugates (ADCs), as they facilitate the coupling of high ratios of drug molecule per antibody. ADCs conjugated via multi-arm PEGs deliver a higher concentration of drugs to targets for each antibody-antigen interaction and exhibit improved solubility and PK/PD profile.
- Monodispersed Linear PEGs
- PEG oligomers with monodispersed molecular weight distribution for your precise synthesis and conjugation.
- Monofunctional Linear PEGs
- Monofunctional Linear PEGs
- Homobifunctional Linear PEGs
- Choices of Diacrylate, Dimethacrylate, Divinylsulfone; Dialkyne, Diazide; Dithiol, Dimaleimide; Diepoxy; Dibiotin; Diamine; Diisocyanate; Dialdehyde; Disuccinimidyl carbonate; Disilane; Dicarboxylic acid, Diglutaric acid, Diglutamidyl acid; DiIodoacetyl, Bis(nitrophenyl carbonate), orthopyridyl disulfide, Dihydroxyl for your customized crosslinking and conjugation

- Heterobifunctional Linear PEGs
- Various of combination of two different functional groups at PEG terminals
- Multi-arm heterobifunctional PEG derivatives for antibody-drug conjugation (ADCs) as regular products or through custom synthesis. ADCs conjugated via multi-arm PEGs deliver a higher concentration of drugs to targets for each antibody-antigen interaction and exhibit improved solubility and PK/PD profile
- 2-Arm PEGs
- Multi-arm PEG derivatives useful for hydrogel crosslinking and surface coating
- 4-Arm PEGs
- Multi-arm PEG derivatives useful for hydrogel crosslinking and surface coating
- 8-Arm PEGs
- Multi-arm PEG derivatives useful for hydrogel crosslinking and surface coating
Key benefits:
- Wide coverage of functional groups useful for different conjugation/crosslinking reactions
- Various of density of the functional groups or different chemical geometries useful for fabricating biomaterials with controllable mechanical properties
- Active building blocks for different biomaterial fabrications
- From non-GMP small laboratory scale, to commercial scale in GMP and non-GMP grade
Application candidates:
- Biomaterials (i.e. hydrogels) with non-immune response
- Non-fibrosis surface coating applications
- Antibacterial applications
- Nanomaterial modifications for long-term circulation purpose
