What is the Net Content (Peptide Content) of Peptide and What is its Significance?

The weight of dry peptide contains not only the peptide but also some non-peptide components such as water, absorbed solvent, ligand ions and salt. The net content of peptide is the weight percentage of peptide in it, this percentage has a wide range of values, may be from 50% to 90%, depending on the purity, sequence and the method of synthesis and purification, do not confuse the net content of peptide with the purity of peptide, they are two completely different concepts. Purity is usually determined by HPLC. The purity is defined as the percentage of peptide samples containing the correct sequence of components, while the net peptide content is the percentage of peptides in the sample relative to non-peptides, and the net peptide content is usually determined by amino acid fraction analysis or UV spectroscopy.  Since the net peptide content can serve as an important standard, it is vital for calculating the peptide concentration in some experiments that are sensitive to it.

How to Store the Synthesized Peptide?

How to Store the Synthesized Peptide?

Due to the difference in porprotions of net peptide content in drugs, peptides generally need to be stored away from light for long term storage and should be stored at -20 degrees, and can be stored at 4 degrees for short term. It can be transported at room temperature for a short time. Peptides are stable at -20°C, especially after being freeze dried and stored in desiccators. Before exposing them to air, freeze dried peptides can be put at room temperature. This will be less affected by humidity, and when freeze-drying is not possible, the best method is to store them in small working sample volumes. For Cys, Met or TrP containing peptides, deoxidation buffer is essential for their solubilization, because such types of peptides can be easily oxidized by air, and the slow flow of nitrogen or argon through the peptide before sealing the bottle will also reduce the oxidation effect. Peptides containing Gln or Asn are also susceptible to degradation, and all these peptides have a limited life span compared to those that do not contain these problematic simple ones. If you want to buy bulk peptides, the folowwing part will be convenient for you to make inquiry.
