Quick Answer
Lyophilized peptides should be stored at -20°C. Reconstituted peptides should be stored at 2–8°C and used within the specified stability window.
Proper peptide storage is critical for maintaining research compound integrity. Lyophilized (freeze-dried) peptides are generally stable at -20°C for extended periods. Once reconstituted in bacteriostatic water or sterile water, peptides should be stored at 2–8°C (standard refrigerator temperature) and used within the manufacturer's recommended window — typically 14–28 days depending on the compound. Key considerations: avoid repeated freeze-thaw cycles, protect light-sensitive compounds (semaglutide, CJC-1295), handle hygroscopic compounds (NAD+) in low-humidity environments, and aliquot reconstituted peptides for single-use to prevent degradation.
More FAQs
BPC-157 is a synthetic 15-amino acid peptide fragment derived from human gastric juice protein, studied for tissue repair via VEGF upregulation and nitric oxide modulation.
What is Semaglutide?Semaglutide is a long-acting GLP-1 receptor agonist with 94% homology to native GLP-1, modified for extended half-life via albumin binding.
How do peptides work?Peptides are short chains of amino acids that bind specific receptors to trigger intracellular signaling cascades, modulating biological processes at the molecular level.
What is Tirzepatide?Tirzepatide is a dual GIP/GLP-1 receptor agonist — the first compound to simultaneously target both incretin receptors for synergistic metabolic research.
What does peptide purity mean?Peptide purity refers to the percentage of the target compound in the sample, measured by HPLC. Research-grade peptides are typically ≥98% pure.
