名稱：Methyltetrazine-PEG4-Maleimide

英文簡介：

A mid-length, sulfhydryl-reactive labeling reagent with enhanced water-solubility provided by a PEG4 spacer.

Methyltetrazine-PEG4-Maleimide enables simple and efficient incorporation of a tetrazine moiety onto antibodies, cysteine-containing peptides and other thiol-containing molecules. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water-solubility that is transferred to the labeled molecule, thus reducing aggregation of labeled proteins stored in the solution.

名稱：ThioLinker-Tetrazine

英文簡介：

A unique, thiol-reactive, labeling reagent that overcomes drawbacks associated with the use of traditional sulfhydryl labeling chemistry.

The traditional sulfhydryl labeling chemistry cleaves disulfide bridges and leaves them in “open form”, which may compromise the stability and function of an antibody or other proteins. ThioLinkerTM-Tetrazine re-bridges the disulfide bond, and enhances the structural stability of the protein. In addition, conjugates prepared with ThioLinkerTM reagents benefits from reduced heterogeneity and better stability.
