Lissamine rhodamine B PEG3 azide (Sulforhodamine B PEG3 azide) is an excellent alkyne-reactive fluorescent reagent for labeling alkyne-containing biological molecules through click chemistry

Mal-Lys(m-PEG4)-Val-Cit-PAB(m-PEG4)-PNP DBCO 291 SMILES CC(C)(C)OC(=O)N1CCN(CC(O)=O)CC1 Purity (HPLC)SOLU KNEX cleavable linker features a Val Cit dipeptide. In this product, a Mal Lys(m PEG4) moiety replaces the conventional maleimidocaproyl (MC) unit to enhance aqueous solubility. Additionally, m PEG4 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to further increase aqueous solubility. The PNP (para nitrophenyl) moiety serves as an activating leaving group, enabling efficient and selective conjugation of the payload
