Structural Composition and Characteristics
The GE11 peptide is widely recognized in scientific literature, having been identified as a potential EGFR-specific peptide through phage display technology in 2005. Its primary structure is defined by the Tyr-His-Trp-Tyr-Gly-Tyr-Thr-Pro-Gln-Asn-Val-Ile arrangement. In shorthand documentation, this is commonly referred to as YHWYGYTPQNVI. When ordering this for laboratory use, you will oft GE11 | Anticancer Peptide en see it listed as H-Tyr-His-Trp-Tyr-Gly-Tyr-Thr-Pro-Gln-Asn-Val-Ile-OH.
From a technical perspective, the molecule is a dodecapeptide characterized by a hydrophobic region (YHWYG) and a relatively hydrophilic segment (YTPQNVI). This amphiphilic nature is a critical factor when considering its binding efficiency. Researchers often utilize the Y-H-W-Y-G-Y-T-P-Q-N-V-I notation to map out the specific amino acid interactions that facilitate its affinity for target receptors.

Throughout my personal review of relevant studies, I have observed several key configurations:
* Nanocarrier Conjugation: A common modification involves the use of DSPE-PEG2000-GE11, which serves as a specialized lipid component in nanocarrier formulations.
* Linker Integration: To optimize stability and performance, the GE11 peptide with a linker sequence is frequently employed. For instance, the use of (GGGGS)3 linkers has been documented to improve the efficiency of molecular interactions.
* C-Termini Modification: Some experimental protocols involve modifying the GE11 C-termini with a GGGGC sequence to facilitate functionalization with polymers like PEG–PLGA.
* Advanced Imaging: The integration of the peptide into GE11-CSO-SPION micelles has shown promise in MRI-based contrast imaging, providing a clear exam by S Decker·2022·Cited by 12—The peptide sequence of GE11, i.e.YHWYGYTPQNVI, consists of the hydrophobic part YHWYG and the relatively hydrophilic region YTPQNVI.

Insights for Experimental Design
When working with the GE11 sequence, it is important to account for the specific binding kinetics. Studies have indicated that the peptide GE11 binds with a dissociation constant (Kd) in the nanomolar range. by L Zhang·2023·Cited by 5—HBcsequencewas synthesized by the company, and theGE11 peptidewas inserted into the MIR region by SphI single enzyme digestion. TheGE11-HBc was attached to Read more However, for those looking to replicate results, it is worth noting that the GE11 peptide is often synthesized with modifications. I have encountered instances where two GE11 peptide nucleotide sequences are linked together to enhance the binding avidity of the final construct.
Furthermore, when comparing different batches or suppliers, always verify the purity and the specific GE11 sequence provided. While the core YHWYGYTPQN motif remains consistent, variations such as YHWYGYTPENVI are sometimes explored to test the impact of single amino acid substitutions on binding behavior.
Final Reflections
The GE11 peptide remains a cornerstone in the study of ligand-receptor interactions. Whether you are working with GE11 peptide-conjugated liposomes or exploring the structural integrity of the GE11 sequence in various buffer systems, the precision of the amino acid arrangement is paramount. By focusing on the high-quality synthesis of peptide 1 (GE11, Table 1) and ensuring that the GE11 peptide is handled according to standard laboratory safety protocols, researchers can continue to push the boundaries of molecular targeting experiments.
In my experience, maintaining a rigorous focus by P Ghosh·2026—(a)Sequenceof peptides GE137 andGE11used for binding MET and EGFR synthesis of the linearpeptide GE11proved straightforward.
