Description:

3-sn-Phosphatidyl-L-serine (PS) conjugated Polyethylene Glycol, PS PEG is a phospholipid PEG conjugate which has both hydrophilicity and hydrophobility. Pegylated phospholipids are excellent liposome formation materials that can be used for drug delivery, gene transfection and vaccine delivery as well. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drugs. These materials can also be used for targeted drug delivery by modifying their surfaces with targeting ligands such as antibodies, peptides.

Description:

4 arm PEG maleimide is one of Nanocs multiarmed PEG derivatives have multiple reactive maleimide groups that can be used to modify proteins, peptides and other materials via their functional groups. 4 arm Maleimide PEG has been used to synthesize hydrogel and modify nanoparticle surface. Maleimide reacts with thiol group rapidly at neutral pH to form stable thioether bond. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces. .

  • Form: Solid to semi-solid
  • Color: white to Off-white/white
  • Solubility: Soluble in water
  • Reactive group: Maleimide
  • Reactive to: Thiol
  • Purity: >95%

Description:

Maleimide PEG DBCO (dibenzocycolctyne) is one of Nanocs DBCO PEG derivatives that can go Click Chemistry reaction without a need of any metal catalysts. The strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also termed as the Cu-free click reaction, is a bioorthogonal reaction that enables the conjugation of two molecules in aqueous solution. DBCO PEG derivatives possess fast kinetics and stability in aqueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. Meanwhile, maleimide group can react with sulfhydryl (Thoil) groups at pH 6.5-7.5 easily. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

  • White/off-white solid or viscous liquid depends on molecule weight;
  • Soluble in aqeous buffer and DMSO;

Copper-free Click reaction procedures:

  • Prepare the azide-containing reagents in reaction buffer.
  • Add DBCO reagents to azide containing reagents. Add 1 mol equivalent of limiting reagent to 1.5~3.0 mol equivalents of abundance reagent.
  • Incubate the reaction at room temperature for 2~4 hours or 2~12 hours at 4 0C.
  • Purify conjugates either by dialysis or size-exclusion chromatograph.

Storage Conditions:

  • Store at -20 0C. Desiccate. Protect from light. Avoid frequent thaw and freeze.
