Mastering Peptide Storage & Handling: A Guide by Sgreats Peptide

To ensure the integrity of your research, proper handling and storage of peptides are critical. At Sgreats Peptide, we provide high-purity lyophilized peptides designed for excellence. Here is everything you need to know about maintaining their stability.

1. Upon Arrival: Appearance & Initial Check

All Sgreats Peptides are shipped at ambient temperature via reliable carriers (FedEx, DHL, etc.) in a stable, lyophilized (freeze-dried) powderform.
  • Volume Variance:You may notice different powder volumes in tubes containing the same quantity; this is normal and depends on the specific sequence.
  • Hygroscopy:Some short sequences are highly hygroscopic (absorb moisture) and may appear as a gel or transparent film. This does not affect the peptide’s quality or mass.

2. Storage Guidelines

  • Short-Term (Days to Weeks):Lyophilized powders are stable at room temperature, but we recommend storing them at 4°Cand protecting them from intense light to ensure maximum activity.
  • Long-Term (>4 Weeks):For extended storage, keep peptides at -20°C or -80°C. When stored properly in powder form, they remain stable for years.

3. Handling Peptides in Solution

Peptides are significantly less stable once reconstituted. To prolong their shelf life in liquid form:
  • Aliquot is Key:Divide your solution into single-use aliquots before freezing. This avoids freeze-thaw cycles, which rapidly degrade peptide bonds.
  • Optimal Conditions:A pH of 5–7is ideal for most sequences. Use anhydrous (dry) organic solvents for stock solutions to prevent premature hydrolysis.
  • Shelf Life:Generally, solutions last 1–2 weeks at 4°C, 3–4 months at -20°C, and up to 1 year at -80°C.

4. Pro-Tips for Accuracy

  • Weighing:If you must weigh the powder, do it quickly. Peptides absorb atmospheric water almost instantly.
  • Sgreats Advantage:To save time and ensure precision, ask us about our pre-aliquoting servicewhen placing your order.

5. Safety First

While Sgreats Peptide produces high-quality research materials, the specific toxicity of every custom sequence is not always known.
  • Handle with Caution:Lyophilized powders can be volatile.
  • Mandatory PPE:Always wear gloves, masks, and safety glasses.
  • Environment:Work in a clean, well-ventilated laboratory setting.
