Peptide stability is a critical factor in research reproducibility. Improper storage can lead to degradation, aggregation, and loss of biological activity. This guide covers essential protocols for handling research-grade peptides.
Store at -20°C in a desiccated environment. Most lyophilized peptides remain stable for 24+ months when stored properly. Avoid repeated freeze-thaw cycles.
Once reconstituted, peptides should be aliquoted into single-use volumes and stored at -20°C. Working solutions at 2-8°C are typically stable for 7-14 days depending on the peptide.
