MtoZ Biolabs provides partition chromatography peptide purification service based on the principle of liquid-liquid partition chromatography to offer high-resolution and high-recovery peptide purification solutions for research and biopharmaceutical clients. This service is suitable for natural peptides, synthetic peptides, and recombinant peptide samples, enabling high-purity separation and impurity removal of target peptides from complex samples to ensure reliable mass spectrometry identification, structural determination, and functional validation.
Principle of Partition Chromatography
Partition Chromatography is a liquid chromatographic technique that separates components based on their distribution coefficient differences between two phases.
Fundamental Principle: Solutes are continuously partitioned between the stationary and mobile phases, achieving separation according to their solubility differences in the two phases.
Typical Modes: Include liquid-liquid partition and liquid-solid partition, mostly using polar solvent systems.
Separation Characteristics: Suitable for separating polar or moderately polar peptides with a mild retention mechanism that does not disrupt peptide structure or bioactivity.

This method combines selectivity and reproducibility and can be coupled with mass spectrometry or other analytical platforms for target peptide purification and quantitative analysis.

Q3: How should I prepare my samples?
To ensure accurate and reproducible peptide purification results, MtoZ Biolabs recommends the following preparation guidelines:
1. Sample Type: Acceptable forms include synthetic peptides, recombinant peptides, and peptide mixtures derived from biological samples
2. Sample Purity: Samples should be free of high concentrations of salts, surfactants, or organic solvents that may affect partition equilibrium or chromatographic performance
3. Amount Requirement: At least 1–2 mg of peptide or ≥500 µL of peptide solution is recommended for standard purification workflows
4. Storage and Shipping: Store samples at −20°C (synthetic peptides) or −80°C (recombinant or natural samples). Ship on dry ice in sealed, leak-proof containers to preserve integrity
5. Documentation: Include details such as peptide source, solvent composition, concentration, and intended purification goal
