- Description
Mal-PEG1-SPA is a PEG-based bioconjugation linker with maleimide and NHS ester functional groups. The maleimide reacts with thiols to form covalent bonds, while the NHS ester couples with primary amines to produce amide linkages. Its single-unit PEG spacer supports water solubility and reduces steric hindrance.
Also named Mal-PEG1-NHS ester, this reagent is used in antibody-drug conjugate and PROTAC research. The catalog lists a molecular formula of C13H14N2O7, a molecular weight of 310.26, and purity of ≥95%.
