DBCO-PEG4-DBCO is a PROTAC connection bridge, belonging to the Polyethylene glycol (PEG) category. DBCO-PEG4-DBCO may be utilized to prepare a veriety of PROTAC protein degraders. DBCO-PEG4-DBCO is a cleavable ADC bridge used for the synthesis of antibody active molecule conjugates (ADCs). DBCO-PEG4-DBCO is a reagent for click chemistry. It has a DBCO group and could undergo SPAAC (Strain-promoted alkyne-azide cycloaddition) with compounds bearing an Azide (N3) moiety.

Biological Activity


ln Vitro Two distinct ligands, one for the E3 ubiquitin ligase and the other for the target protein, are present in PROTAC and are joined by a linker. PROTAC targets and selectively degrades target proteins by means of the intracellular ubiquitin-proteasome system. An ADC cytotoxin is connected to an antibody by use of an ADC linker to form an ADC.

Solubility Data


Solubility (In Vitro) DMSO : ~100 mg/mL (~123.32 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (3.08 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: 2.5 mg/mL (3.08 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: ≥ 2.5 mg/mL (3.08 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.2332 mL 6.1658 mL 12.3315 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
