PC Methyltetrazine-PEG4-NHS carbonate ester CAS:2055736-28-0 is a type of PEGylation reagent commonly used in the field of pharmaceutical research and development. It contains an NHS carbonate ester functional group, which enables it to covalently attach to amino groups on a variety of biological molecules, such as proteins, peptides, and antibodies.
By modifying these molecules with PC Methyltetrazine-PEG4-NHS carbonate ester, their solubility, stability, and pharmacokinetic properties can be improved, leading to enhanced therapeutic efficacy and reduced toxicity. Furthermore, the tetrazine group on the PEG4 spacer arm enables selective and efficient bioorthogonal click reactions with trans-cyclooctene (TCO) or other tetrazine-modified molecules, providing a versatile tool for drug conjugation, imaging, and diagnostic applications.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
