The water soluble 5(6)-FAM PEG3 azide (protected) has a long PEG3 spacer that separates the dye carboxyfluorescein (commonly known as FAM) from the terminal azide group

Mal-Acetyl-Dap(m-PEG4)-Val-Cit-PAB(m-PEG4) new Product Name: 6-FAM Synonyms: 6-CarboxyfluoresceinSOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Mal Acetyl Dap(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. The Mal Acetyl group may also improve retro Michael addition stability during antibody conjugation. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. Derived from established
