Small Peptide Purification Service

MtoZ Biolabs provides small peptide purification service using multidimensional chromatographic technologies such as RP-HPLC, IEC, and HILIC to achieve efficient separation and purification of small peptide samples. This service offers stable and reliable small peptide products for research institutions and biopharmaceutical companies, supporting structural analysis, activity validation, and downstream development. The goal is to improve small peptide sample quality and ensure smooth downstream analysis and applications.

 

What is Small Peptide

Small peptides typically refer to peptide molecules composed of 2 to 20 amino acids. They have low molecular weight, simple structure, high solubility, and are relatively easy to purify. These peptides are widely present in biological systems and participate in signaling, metabolic regulation, and cellular communication. They hold significant value in drug development and biomarker discovery. Small peptides show high flexibility and good chemical stability and are suitable for various biochemical and molecular biology studies.

Q3: How should I prepare my samples?

To ensure accurate and reproducible results for the Small Peptide Purification Service, MtoZ Biolabs recommends:

1. Providing 2 to 5 mg of crude peptide or an equivalent amount of peptide mixture

2. Avoiding high salt, strong acids, strong bases, and surfactants that may interfere with separation or detection

3. Submitting lyophilized powder whenever possible, or storing solutions at minus 20 degrees Celsius or minus 80 degrees Celsius and shipping on dry ice

4. Supplying complete background information, including sequence, modifications, theoretical molecular weight, initial purity, buffer system, and target purity
