Azide-Dap(m-PEG4)-Val-Ala-OH halotag NCCCCCCNC1=C2CN(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC) >= 95%SOLU KNEX cleavable linker features a Val Ala dipeptide. In this product, a Azide Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The azide functional group is widely utilized in bioconjugation via click chemistry to enable efficient and selective attachment of biomolecules. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing moietiessuch as PEG, amine
