| Targets |
3X FLAG Peptide targets anti-FLAG antibodies, specifically competing for binding to the antibody's antigen-binding site. It does not have a biological target in the traditional sense of a drug. By binding to the antibody, it displaces the FLAG-tagged protein of interest, allowing for its gentle elution under native conditions.
|
|---|---|
| ln Vitro |
3X FLAG peptides can be applied to compounds such as proteins.
In vitro, 3X FLAG Peptide is used as a competitive reagent in immunoprecipitation and protein purification workflows. It is effective at eluting FLAG-tagged proteins from anti-FLAG affinity gels. Its activity is assessed by its ability to efficiently release the target protein while maintaining its functionality, as opposed to harsh acidic elution methods. |
| ln Vivo |
In vivo activity is not applicable for 3X FLAG Peptide, as it is a reagent used for in vitro protein isolation and characterization. It is not a drug and is not intended for administration to living organisms for therapeutic purposes.
|
| Enzyme Assay |
In vitro binding assays for 3X FLAG Peptide are not typically performed. Instead, its efficacy is validated through its use in standard protein purification protocols. The peptide's ability to compete with a FLAG-tagged protein for binding to an anti-FLAG antibody is demonstrated by Western blot or by measuring the concentration of eluted protein.
|
| Cell Assay |
In vitro cellular studies for 3X FLAG Peptide are not typical, as it is not a drug. However, it can be used in cell lysates for immunoprecipitation experiments. Cells expressing a FLAG-tagged protein are lysed, and the protein of interest is captured on anti-FLAG antibody beads. The 3X FLAG Peptide is then applied to elute the protein from the beads.
|
| Animal Protocol |
In vivo animal experiments are not applicable for 3X FLAG Peptide. It is strictly a laboratory reagent for protein biochemistry and is not used in animal studies for therapeutic or pharmacological evaluation.
|
| ADME/Pharmacokinetics |
3X FLAG Peptide has a molecular weight that varies depending on the source (e.g., 1913.90 g/mol or 2861.87 g/mol) and a molecular formula (e.g., C120H169N31O49S). It is supplied as a lyophilized powder. It is soluble in aqueous buffers. For storage, it is typically kept at -20°C. It is highly pure, often >98%.
|
| Toxicity/Toxicokinetics |
As a peptide, 3X FLAG Peptide is not associated with significant toxicity. It is a laboratory reagent and is not intended for human or animal consumption. Standard laboratory safety precautions should be followed when handling it.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
