MC-Val-Cit-PAB-PNP is a cleavable ADC linker which contains a maleimide, a valine-citrulline (Val-Cit dipeptide, and a para-nitrophenyl (PNP) group. Maleimide is a thiol-specific covalent linker which is used to label cysteine residues in proteins while the PNP carbonate acts as a highly activated leaving group which may be used to react with amines. Val-Cit linkers are cleaved by Cathepsin B.

Active-Mono-Sulfone-PEG8-acid is a PEG linker with a sulfone and acid end group. The sulfone group can be conjugated with thiol groups of proteins. The terminal carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to from stable amide bonds. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-sulfone-PEG12-NHS Ester is a bis-alkylating labeling reagent that is selective for the cysteine sulfur atoms from a native disulfide. These reagents undergo bis-alkylation to conjugate both thiols derived from the two cysteine residues of a reduced native disulfide bond such as the interchain disulfide bonds of an antibody. The reaction results in covalent rebridging of the disulfide bond via a three carbon bridge leaving the protein structurally intact. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
