Description

(+)-Biotin-PEG12-NH-Mal refers to a specific structure where biotin is linked to a 12-unit polyethylene glycol (PEG) chain, terminating in a maleimide (Mal) functional group through an amine (NH) linker. Biotin-PEG12-NH-Mal can be used to selectively label proteins or peptides that have exposed cysteine residues. The maleimide group reacts specifically with thiols (–SH) to form stable thioether bonds, allowing precise conjugation.
