Chemical information
Chemical and common name: G2-peptide. Molecular formula: C90H155N13O54. Molecular weight: 2283.27 g/mol. CAS number: 361443-81-4. Classification: SGP Products.
Design features
Engineered peptide sequences can favor specific conformations, such as helices or turns, to support recognition of a target. Depending on the construct, non-natural residues or terminal modifications such as acetylation or amidation can improve resistance to enzymatic degradation. Selected positions can serve as attachment points for reporters, including fluorescent labels and biotin, as well as payloads and linkers.
Applications
Target validation and delivery
Peptide tools can mimic or block protein–protein interaction surfaces, helping to validate disease-related targets or identify starting points for peptide drug design. Targeting sequences can also be investigated as carriers for small molecules or nucleic acids in cell- and tissue-specific delivery studies, including oncology models.
Detection and molecular imaging
After selection and validation for binding to a particular biomarker, a peptide can serve as a recognition element in ELISA, immunohistochemistry, or biosensors. Coupling to a radionuclide or near-infrared dye can support research on noninvasive imaging, early detection, and treatment monitoring.
Mechanistic and structural studies
Peptide probes can perturb selected interactions to help characterize signaling pathways in cell or animal models. A defined peptide ligand can also aid co-crystallization with a target protein and structural analysis of its binding interface.
Conclusion
Sequence design and conjugation provide ways to adapt peptide tools to individual research questions, from molecular recognition to exploratory diagnostics and delivery.
