DLPLTFGGGTK TFA（Cat No.:I044197）is a synthetic decapeptide with the sequence Asp-Leu-Pro-Leu-Thr-Phe-Gly-Gly-Gly-Thr-Lys, provided as a trifluoroacetate (TFA) salt. This peptide is commonly used in proteomics, particularly as a tryptic peptide standard or in mass spectrometry calibration due to its defined composition and behavior in analytical systems. The sequence includes hydrophobic and flexible residues, making it suitable for studies on peptide fragmentation patterns, retention times, or protein digestion efficiency. DLPLTFGGGTK TFA serves as a valuable reference or tool in quantitative proteomics, peptide mapping, and method validation for analytical workflows.
