In the landscape of modern molecular biology and protein biochemistry, the ability to isolate and analyze specific proteins with high precision is paramount. Among the various tools available to researchers, the 3x flag peptide genscript has emerged as a gold-standard reagent for those who require robust performance in protein purification and detection.
The S 3X Flag Peptide tructural Precision of the 3x Flag Peptide
The 3X FLAG Peptide is a synthetic peptide of 23 amino acid residue that has become a staple in laboratories worldwide. Unlike the traditional single-copy tag, this construct features a specific design where the core Asp-Tyr-Lys-Xaa-Xaa-Asp motif is repeated three times. This multimeric approach significantly enhances the affinity and sensitivity of the tag, making it an invaluable asset when working with fusion proteins.
From a technical perspective, the molecule is defined by the sequence MDYKDHDGDYKDHDIDYKDDDDK. It is a tricosapeptide with a molecular weight of approximately 2,861.87 Da. Because it is hydrophilic in nature, it remains highly soluble and stable under a variety of experimental conditions, which is why it is commonly used as a protein tag for purification a 3X FLAG® Peptide - Sigma-Aldrich nd detection.
Practical Applications and Experimental Efficiency
When discussing the DYKDDD Genscript Corporation DYKDDDDK Peptide DK Peptide, researchers often emphasize the importance of high purity. Suppliers like GenScript provide this material with purity levels typically exceeding 95%. This high-purity 3X FLAG Peptide ensures that elution processes are both efficient and reproducible.
In practice, the peptide serves as a competitive elution agent.
