CD Bioparticles introduces a series of Cleavable Linkers to accelerate researchers’ studies, including PC Cleavable Linkers, Dde Cleavable Linkers, ß-Glucuronide Linkers, -S-S- Cleavable Linkers, Cleavable Peptide Linkers, and Diazo Biotin Cleavable Linkers. CD Bioparticles has strong and broad expertise and over years of experience in the drug delivery field. The new series of cleavable linkers provide various choices for customers. For instance, the PC Biotin-PEG3-azide. It is PEG derivative containing a biotin group and an azide group. The azide group readily reacts with alkyne, DBCO, and BCN through Click Chemistry reactions to form a stable triazole linkage. The hydrophilic PEG spacer can increase aqueous solubility of the biotin conjugated molecules. It can also help minimize steric hindrance and provide extra flexibility with the binding to stravidin and avidin molecules. One example of Cleavable Peptide Linkers is the Acid-propionylamino-Val-Cit-OH-OH, which is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADC). The Val-Cit is specifically cleaved by cathepsin B. As this enzyme is only present in the lysosome, the ADC payload will be released only in the cell. The Boc group can be deprotected under acidic conditions to generate a free amine group. As for Dde Cleavable Linkers, the example is Dde Biotin-PEG4-DBCO. It is useful for introducing a biotin moiety to alkyne-containing biomolecules using Click Chemistry. The hydrophilic spacer arm improves the solubility of the labeled molecules in aqueous media. Dde protecting group allows efficient release of captured biotinylated molecules from streptavidin/avidin under mild conditions with hydrazine.
