DM3 (Maytansinoid DM3) is a maytansine mimic with disulfide or thiolgroups, acting as a tubulin inhibitor and serving as the cytotoxic component in antibody-drug conjugates (ADCs).
Thiol-PEG3-alcohol is a PEG derivative containing a hydroxyl group and a thiol group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
Maleimide-PEG4-NHS is a sulfhydryl and amine reactive heterofuncational PEG linker. The chemical bonds formed through Maleimide-PEG4-NHS linker are stable and are not cleavable. The NHS ester reacts with amino groups at pH 7-9 to form stable amide bond wh
Bis-PEG5-thiol is a PEG derivative containing two thiolgroups. The thiolgroups react with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG spacer increases solubility in aqueous media.
Thiol-PEG2-acid is a PEG derivative containing a thiol group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond.
