3X Flag Peptide Powder CAS 402750-12-3

3X Flag Peptide Powder is a synthetic 22-amino-acid peptide containing three tandem FLAG epitope sequences. Manufactured via mature solid-phase peptide synthesis (SPPS) under strict GMP conditions, this high-precision peptide undergoes multi-step HPLC purification and ESI-MS structural verification. It delivers ultra-high purity and complete sequence accuracy, serving as a standardized molecular tool for protein purification and molecular biology research.

3X Flag Peptide specifically binds to Anti-FLAG M2 monoclonal antibodies with high affinity. It enables efficient competitive elution of FLAG-tagged recombinant proteins under mild, non-denaturing experimental conditions. This gentle elution mechanism effectively preserves the natural conformation and biological activity of target proteins, providing a reliable and efficient solution for high-purity protein isolation and functional molecular biology experiments.

1. FLAG-tagged protein purification – Core tool for efficient elution and isolation of FLAG-labeled recombinant proteins.

2. Mild non-denaturing elution research – Supports protein elution under gentle conditions to retain native protein activity and structure.

3. Anti-FLAG antibody binding assays – Ideal for antibody affinity detection and epitope binding mechanism verification.

4. Molecular biology experimental research – Widely applied in protein identification, enrichment and related molecular mechanism studies.
