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 and detection.
Practical Applications and E Can 3xFLAG peptide (MDYKDHDGDYKDHDIDYKDDDDK) xperimental Efficiency
When discussing the DYKDDDDK 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. Because the 3xFLAG peptide binds with high specificity to anti-DYKDDDDK antibodies, researchers can use it to displace tagged proteins from affinity resins, such as the GenScript Anti-DYKDDDDK IP Resin, under non-denaturing conditions. This gentle elution method is critical for maintaining the biological activity and structural integrity of the target protein.
Key Considerations for Researchers
For those looking to integrate this into their workflow, it is helpful to understand the nomenclature and specifications:
* Sequence Integrity: The 3X FLAG peptide is a synthetic peptide of 23 amino acid residue that functions effectively due to its optimized design.
* Identification: 3X FLAG peptidecan be used for protein separation and purification, and competitive elution with target proteins. For research use only.Read more Whether you search by catalog number: search or by sequence, ensure the product matches the expected 23-amino acid configuration to avoid compatibility issues.
* Versatility: The 3xFlag system is broadly compatible with various expression systems, including *in vitro* translation.
* Storage: Always adhere to recommended storage protocols (typically -5 to -30°C) to maintain the efficacy of the lyophilized material.
Why Choose High-Purity Variants?
The decision to utilize a high-purity 3X FLAG Peptide often comes down to the sensitivity requirements of the assay. Because the 3x FLAG peptide is a peptide sequence that is formed by the combination of 23 amino acids, any contaminants in the reagent can lead to background noise in Western blots or inconsistent yields during chromatography.
By utilizing consistent, high-quality peptides, laboratories can achieve reliable detection of fusion proteins down to the femtomole range. Whether you are conducting standard immunoprecipitation or complex protein-target interaction studies, the 3X FLAG peptide remains one of the most dependable tools in the molecular toolkit.
