FLAG Peptide Powder CAS 98849-88-8
Product Description
FLAG Peptide Powder is a synthetic hydrophilic octapeptide epitope tag featuring the classic DYKDDDDK amino acid sequence. Manufactured under strict GMP standards via Fmoc solid-phase peptide synthesis (SPPS), the product undergoes multi-step preparative HPLC purification, desalting and sterile lyophilization, presenting as white to off-white lyophilized powder. Strict control over truncated sequences, deletion peptides and isomeric impurities ensures high batch reproducibility and low background interference for precise molecular biology experiments.
As one of the most authoritative and widely applied epitope tagging systems, FLAG peptide features high specificity and hydrophilic properties, bringing minimal interference to target protein structure and bioactivity. It serves as a reliable universal tool for full-cycle recombinant protein research, covering protein expression identification, high-specificity affinity purification and protein–protein interaction mechanism exploration, supporting stable and repeatable molecular biology experimental analysis.
Product Application
1. Recombinant protein expression detection – Core tagging tool for specific identification and expression verification of recombinant proteins.
2. High-purity protein affinity purification – Enables efficient enrichment and high-purity isolation of tagged recombinant proteins.
3. Molecular biology tagging experiments – Applied in stable epitope tagging for diversified protein functional research.
4. Standard protein engineering research – Serves as a standardized reagent for conventional protein engineering and molecular cloning studies.
