R&D Use Only Products supplied for research and development use

PEG linkers are commonly used to adjust spacing, solubility, flexibility, and presentation in conjugation, degrader design, and biomolecule-modification workflows. Selection often depends on linker length, reactive end groups, branching, cleavability, hydrophilicity, and compatibility with the molecules being connected. This category helps users compare linker architectures for conjugation and modular design problems without starting from custom synthesis. It pairs well with biotinylation reagents, degrader building blocks, and PEGylation workflows.
