    Bis-sulfone-PEG3-Azide

    		ADC Linker Cancer
    Bis-sulfone-PEG3-Azide is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Bis-sulfone-PEG3-Azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

    4-(3-Tosyl-2-(tosylmethyl)propanoyl)benzoic acid

    Bis–sulfone Acid

    		 Biochemical Assay Reagents Others
    4-(3-Tosyl-2-(tosylmethyl)propanoyl)benzoic acid (Bis-sulfone Acid) is a strong covalent linker featuring a free carboxylic acid and two tosyl groups. Each tosyl group can be displaced by thiol or amine nucleophiles via a Michael addition, and the inclusion of two on this molecule allow this reaction to proceed twice. This may be used to “staple” two reduced cysteine residues on a given protein to reform disulfide bridges. The carboxylic acid is free to react to form amides or esters.

    Bis-sulfone NHS ester

    		Biochemical Assay Reagents Others
    Bis-sulfone 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.

    Bis-sulfone-PEG4-Tetrazine

    		PROTAC Linkers Cancer
    Bis-sulfone-PEG4-Tetrazine is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs . Bis-sulfone-PEG4-Tetrazine is a click chemistry reagent, it contains a Tetrazine group that can undergo an inverse electron demand Diels-Alder reaction (iEDDA) with molecules containing TCO groups.

  • HY-W800682
    Bis-sulfone-PEG4-acid

    		Biochemical Assay Reagents Others
    Bis-Sulfone-PEG4-acid is a reagent with a sulfone and an acid. The sulfone group can be conjugated with thiol groups of proteins. The terminal acid reacts with primary amines with the help of activators (EDC or HATU) to from stable amide bonds.

    Bis-sulfone-PEG12-NHS ester

    		Biochemical Assay Reagents Others
    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.
