Custom peptides involve more than simply providing an amino acid sequence. This article introduces key factors such as peptide sequence, purity, modifications, cyclization strategies, unnatural amino acids, and AI-assisted design, helping researchers obtain higher-quality peptide products.
The difficulty of peptide synthesis is not determined by chain length alone, but by the combined effects of sequence composition, coupling efficiency, cyclization strategy, and chemical modifications. This article systematically analyzes the key factors that affect the success rate, purity, and purification difficulty of SPPS.
Higher peptide purity is not necessarily better. This article systematically explains the appropriate use cases for crude peptides and peptides with purities of 70%–85%, 95%, 98%, and above 99%, helping users in scientific research and drug development select a more appropriate purity grade based on their experimental objectives.
95% purity is typically the standard specification for research-grade peptides. This article analyzes its suitability for cell-based experiments, protein interactions, antibody development, and functional validation, and explains when it is necessary to select a purity of 98% or 99% or higher.
Peptide salt forms can affect solubility, biocompatibility, actual content, and performance in certain experimental systems. This article introduces the differences among TFA Salt, Acetate Salt, HCl Salt, and Free Form, and explains how to select an appropriate salt form for different application scenarios.
Peptide solubility is closely related to sequence composition, net charge, hydrophobicity, length, cyclization, and chemical modifications. This article introduces commonly used dissolution strategies for different types of peptides to help customers select appropriate solvents based on the sequence.
