In the specialized field of biochemical research, the focus on molecular targeting has led to significant interest in specific ligands. Among these, the G11 peptide (often referred to in literature as GE11) has emerged as a subject of intense study due to its unique structural properties and its ability to interact with cellular receptors. As someone deeply involved in the procurement and analysis of high-purity research compounds, I by B Judmann · 2023 · Cited by 7 — RGD-GE11 peptide for dual integrin and EGFR-targeted tumour imaging. EGFR-targeting peptide GE11 as a potential PET tracer. Amino Acids have found that understanding the technical nuances of these molecules is essential for any rigorous investigative work.
Structural Characteristics and Ligand Affinity
The G11 peptide is a dodecapeptide, mea Challenges for the application of EGFR-targeting peptide ning it consists of a chain of 12 amino acids. Its primary utility in research stems from its role as a potent EGFR ligand. Unlike natural epidermal growth factor (EGF), which can induce mitogenic effects, the GE11 peptide is specifically valued because it binds to the EGFR region with high affinity and selectivity without the same proliferative risks.
When reviewing technical specificatio GE11 Peptide as an Active Targeting Agent in Antitumor ns, it is clear that GE11 is a small peptide with 12 amino acids, which provides a distinct advantage in conjugation chemistry. Because it is much smaller by D Hu · 2016 · Cited by 63 — GE11 peptide modified and reduction-responsive hyaluronic acid-based nanoparticles induced higher efficacy of doxorubicin for breast than native EGF, it offers superior flexibility when being integrated into complex delivery platforms.
Applications in Targeted Research
My experience with these compounds confirms that G11 Peptides supplies high-purity research peptides that are essential for consistent experimental outcomes. Researchers often utilize this molecule in several sophisticated ways:
* Gene Delivery: GE11 has been used as a gene delivery vehicle, often conjugated to polymers like polyethylenimine (PEI) to improve the precision of genetic material transport.
* Nanoparticle Conjugation: The peptide is frequently conjugated to nanoparticles. For instance, GE11 was conjugated to the nanoparticles to increase the localized concentration of investigative agents.
* Drug Delivery Systems: As an active peptide, it is often combined with colloidal drug delivery systems, acting as a smart carrier. One notable advancement is the GE11-active tumor targeting and pH-responsive co-delivery micellar system, which utilizes the peptide to guide therapeutic payloads to specific sites.
* Imaging and Diagnostics: Because of its specificity, the EGFR-targeting peptide GE11 is increasingly studied as a potential tracer in molecular imaging, helping to visualize receptor expression in controlled in-vitro environments.
E-E-A-T and Technical Considerati GE11 Peptide Conjugated Liposomes for EGFR-Targeted ons
For those sourcing these compounds, quality control is paramount. Research-grade peptides must be lyophilized to ensure long-term stability and purity. When evaluating suppliers, I look for documentation regarding the CAS number (875142-25-9) and evidence of Radiocobalt-Labeling of a Polypyridylamine Chelate high-performance liquid chromatography (HPLC) analysis.
While some researchers might confuse this with other hormonal peptides, such as Glucagon-like peptide-1 (GLP-1), it is vital to maintain a clear distinction. GLP-1 is a natural gut hormone by T Hailing · 2022 · Cited by 56 — GE11 peptide is one of the potent EGFR ligand screened from a phage display peptide library. It is a dodecapeptide that can specifically binds to EGFR with involved in metabolic regulation, whereas the G11 peptide is strictly categorized as an EGFR-specific ligand for laboratory use.
Implementation Strategies
In practice, the success of using GE11 depends on the conjugation strategy. Whether it is used to selectively deliver loading drugs into cancer cells or to study the binding kinetics of EGFR, the orientation of the peptide remains critical. Data indicates by M Hallaji · 2025 · Cited by 13 — Previous studies have demonstrated that the GE11 peptide exhibits a high affinity for the EGFR, and can effectively target cancer cells that that GE11 has been widely used in the diagnosis and targeted delivery of drugs, highlighting its versatility in experimental oncology models.
When exploring the literature—where it is often listed as Peptide 1 (or GE11, Table 1)—one can see that its dissociation constant and binding affinity make it a gold standard for studies involving receptor-overexpressing models. If you are beginning your own investigation into this compound, prioritize suppliers who provide transparent batch testing, as the consistency of the peptide sequence is the foundation of reproducible research.
