Description:

DBCO (dibenzocycolctyne) PEG thiol (DBCO-PEG-SH) derivatives 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. 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 solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

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.

Similar names: Aminooxy PEG Thiol, Oxyamine PEG Thiol, HS-PEG-ONH2, Thiol PEG Oxyamine

Thiol PEG Aminooxy (HS-PEG-ONH2) is one of Nanocs heterobifunctional crosslinker PEGs that has a free thiol/sulfhydryl group on one end of PEG terminus and an aminooxy (-ONH2) functional group on the other PEG  terminus. Thiol group can bind to gold and other surface,  it can also react with many thiol reaction groups such as maleimide. Aminooxy group (-ONH2), on the other hand, can react with carbonyl groups with good stability. PEG linker between thiol and aminooxy offers better solublity and reduced steric hindrance.

Product specifications:

  • Form: Solid powder or semi-solid depends on molecular weight of PEG;
  • Functional groups: Sulfhydryl (-SH) and aminooxy (-ONH2);
  • Reactive to: Maleimide, metal surface, etc and carbonyl;
  • Solubility: Soluble in aqueous solution;

Storage:

  • Store at -20 0C.

Description:

Ethoxy or methoxyl silane functionalized polyethylene glycol, silane PEG (PEG-Si) is a surface reactive PEG derivative that can be used to modify glass, silica and other surfaces via the reaction between hydroxyl group and ethoxyl/methoxyl silane. Pegylation can greatly suppress the non-specific binding of charged molecules to the modified surfaces. And they have wide applications for medica device, biomems or biocompatible material development.

Physical Properties:

  • Off-white/white solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C, desiccated. Silane PEG tends to hydrolyze from moisture. Avoid frequent thaw and frozen.

Reaction Procedures:

Generally, silane PEG is first dissolved in a mixture of ethanol/water solution, then allow the solution to contact with oxidized glass or silica surface for 30 min to 2 hours. Under this condition, silane PEG should bind to the material covalently.

Materials Required:

  • Pegylation solution: Ethanol/water (w/w, 95%/5%);
  • Silane PEG stock solution, 10~50 mg/mL in pegylation solution, prepare in fresh.
  • Washing solution: Distilled water.

Reaction Steps:

1. Dissolve targeted materials in Pegylation buffer.

2. Add silane PEG stock solution to the targeted conjugation materials with the final concentration keep at least 10 mg/mL. 10~50 molar excess of silane PEG needed for optimal conjugation;

3. Allow mixture agitates at room temperature for 30 min at room temperature or 2 hours at 4 -20 0C.

4. Wash out unreacted materials either by distilled water.
