m-PEG13-acid is a methoxy polyethylene glycol (mPEG) linker bearing a terminal carboxylic acid. It functions as a hydrophilic spacer for bioconjugation and biochemical assays; the terminal carboxyl can be activated (for example with EDC or HATU) and coupled to primary amines to form stable amide bonds, while the PEG spacer enhances aqueous solubility.
