Peptide Library Services: Storage and Handling

Organic chemistry is very broad and can also be used to produce different peptides. Research is ongoing to make it prominent in the basic physiological and biochemical functions of life. They have recently identified techniques for manufacturing and researching new applications.

Peptide library service is a technology that can study proteins and their synthesis. It contains a large number of systematic amino acid combinations, providing a powerful tool for drug design, protein-protein interactions, and other biochemical and pharmaceutical applications. This is a challenging procedure that requires certain precautions in handling and storage. Only proper peptide processing and solubilization can make a bioassay project successful. As one of the most reliable and responsible peptide api manufacturers, we can help you in this field.

1. Peptide library services: storage

Peptide solutions have a limited shelf life, especially peptides containing C, M, N, Q, and W. To prolong the shelf life of peptides in solution, store peptide library services in a dry, cool, and dark place. Sterile buffers with a pH of about 5-6 may be helpful. Store at 4 degrees Celsius and in a cooler place without bright light. Avoid frost-free refrigerators, as repeated freeze-thaw cycles are detrimental to peptides. Generally, a list of peptide drugs is included in the library. Dry peptides can exist for days or weeks at normal room temperature. But solid peptides showed more water contamination. It is recommended to warm the vial to room temperature before opening it. After taking the required amount, reseal the vial and store it in the refrigerator.

2. Peptide library services: peptide dissolution

Also as one of the leading peptide suppliers, we provide detailed information. There is no universal solvent that will dissolve all lyophilized peptides while maintaining their integrity and compatibility in bioassays. Solubility has always been an issue for many peptide library service providers. Therefore, it is necessary to check the dissolution of the peptide using a range of solvents. There are three best ways you can find answers to your peptide solubility questions.

Method 1: Dissolve peptides in sterile distilled water or dilute acetic acid solutions to provide higher concentrations. It will be diluted with the appropriate buffer later. Sonication can even be used to increase dissolution.

Method 2: If the peptide is still insoluble, check the ratio of hydrophobicity, hydrophilicity, and total charge at neutral pH. If there is a net charge at neutral pH, add dilute acetic acid or dilute ammonia or ammonium bicarbonate. If the sample still refuses to dissolve, then try an alternative solvent with the same peptide.

Method 3: If the peptide sequence has little or no charge at any pH, add acetonitrile, ethanol, dimethylformamide (DMF), dimethylsulfoxide (DMSO), and chaotropic salts for better Soluble most peptides. This depends on the choice and compatibility of the reagent with the peptide.

After receiving your peptide from the peptide synthesis company, please follow the storage and dissolution methods above. Because these are more easily degraded by proteases of bacterial or microbial origin. All these peptide library services will definitely help with the long-term storage of peptide libraries.
