| | Propargyl-PEG4-acid Usage And Synthesis |
| Description | Propargyl-PEG4-acid is a PEG reagent with an alkyne and a terminal carboxylic acid. The carboxylic acid reacts with primary amine groups with the help of activators (e.g. EDC, or HATU). The 4-unit PEG spacer increases hydrophilicity. The alkyne can participate in copper-catalyzed Click Chemistry. | | Uses | This heterobifunctional, PEGylated crosslinker features a carboxylic acid at one end and propargyl group at the other for reaction with azide-containing compounds using click chemistry. The hydrophillic PEG linker facilitates solubility in biological applications. Propargyl-PEG4-acid can be used for bioconjugation or as a building block for synthesis of small molecules, conjugates of small molecules and/or biomolecules, or other tool compounds for chemical biology and medicinal chemistry that require ligation. Examples of applications include its synthetic incorporation into antibody-drug conjugates or proteolysis-targeting chimeras (PROTAC? molecules) for targeted protein degradation. | | reaction suitability | reagent type: linker | | IC 50 | PEGs |
