MtoZ Biolabs provides peptide related impurity analysis service based on high-resolution mass spectrometry (HRMS) and multidimensional liquid chromatography (HPLC) platforms to accurately identify, quantify, and characterize impurities in peptide drugs and research-grade samples. This service is specifically designed to support peptide drug development, quality control, and regulatory submission. It helps research and pharmaceutical clients identify peptide-related impurities formed during synthesis, purification, and storage, assess potential safety and immunogenicity risks, and ensure product purity, stability, and batch-to-batch consistency.
What is Peptide Related Impurity
Peptide related impurities refer to non-target peptide components generated during peptide synthesis, purification, storage, or transportation. These impurities typically include:
🔹 Process-Related Impurities: Incomplete coupling, racemization, incomplete deprotection, sequence deletion, or insertion.
🔹 Chemical Modification Products: Oxidation, isomerization, deamidation, disulfide bond reshuffling, or dimerization.
🔹 Degradation or Aging Products: Structural damage caused by storage conditions, pH changes, light exposure, or temperature fluctuations.
🔹 Novel Impurities: Newly formed peptide variants introduced during generic peptide production or process modification.

These impurities may affect the biological activity, safety, and immunogenicity of the drug, and therefore must be accurately identified and controlled during peptide drug development and quality management.

Q3: How should I prepare my samples?
A3: To ensure accuracy and reproducibility of peptide-related impurity analysis, MtoZ Biolabs recommends the following sample preparation guidelines:
1. Sample Types: Accepting synthetic peptides, peptide drug formulations, intermediates, and high-purity research-grade peptides.
2. Sample Purity: Samples should be free of insoluble particles and avoid high concentrations of salts, detergents, or organic solvents that may interfere with chromatographic separation or ionization.
3. Sample Quantity: At least 1 mg of solid sample or 500 μL of liquid sample. Provide additional material if replicate or orthogonal validation is required.
4. Storage and Shipping: Store samples at −20°C or lower in the dark. Ship on dry ice in sealed, leak-proof containers to maintain stability.
5. Accompanying Information: Provide full details including peptide sequence, synthesis or formulation method, buffer composition, and analytical objectives (e.g., impurity types of interest).
