Description

Methyltetrazine-PEG4-SSPy is a cleavable, heterobifunctional linker featuring methyltetrazine for bioorthogonal click chemistry, a disulfide bond for controlled cleavage under reducing conditions, and a pyridyl disulfide (SSPy) group for thiol-specific conjugation. The PEG4 spacer enhances solubility and reduces steric hindrance.


Key Features

  • Methyltetrazine Group
    Enables rapid, selective bioorthogonal IEDDA reactions with strained alkenes (e.g., trans-cyclooctene).
  • Pyridyl Disulfide (SSPy) Group
    Reacts with free thiols to form stable disulfide linkages.
  • Cleavable Disulfide Bond
    Allows controlled molecule release under reducing conditions.
  • PEG4 Spacer
    Enhances solubility and minimizes steric effects during reactions.

Applications

  1. Bioconjugation
    Ideal for dual functionalization of biomolecules, such as proteins and peptides.
  2. Controlled Drug Release
    Facilitates the creation of cleavable drug delivery systems.
  3. Molecular Probes
    Enables the development of functional probes for imaging or diagnostics.
  4. Surface Modification
    Suitable for functionalizing nanoparticles, hydrogels, and other materials.

Short Description
Methyltetrazine-PEG4-SSPy is a cleavable linker with methyltetrazine for IEDDA reactions, SSPy for thiol conjugation, and a disulfide bond for controlled release. Ideal for bioconjugation and drug delivery applications.

AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
