Reconstitution & Handling Guides

Practical guidance for working with EMPYRE BioLabs research peptides. These tips are for reference — always follow your lab's own protocols first.

Reconstitution

How to mix your peptide powder with liquid so it's ready for your experiment.

Let the vial warm to room temperature before you open it. This stops moisture from forming on the powder inside.
Use sterile water to dissolve the peptide. Choose the right amount based on the concentration your experiment needs.
Aim the water at the inside wall of the vial, not straight onto the powder. Let it dissolve on its own. Don't shake or mix hard.
Gently swirl the vial until the powder is gone. If it hasn't dissolved after a few minutes, wait a bit longer at room temperature before swirling again.

How to keep your peptides fresh, whether they are dry powder or already mixed.

Dry peptides: keep the vial sealed in its original packaging at −20 °C, away from light and moisture, until you're ready to use them.
Mixed solutions: store at 2–8 °C if you'll use them soon. For longer storage, split into small portions and freeze at −20 °C. Try not to thaw and re-freeze repeatedly.
Label every portion with the EMPYRE Product ID, date mixed, water type, and strength. Good labeling keeps your experiment organized.
Throw away any mixed peptide that looks cloudy, has particles, or has changed color.

Basic safety rules for working with research peptides in the lab.

Always wear a lab coat, gloves, and eye protection when handling research materials.
Only work with peptides in a clean lab space. Never handle them in a kitchen, home, or patient care area.
Treat all peptides as active biological materials. Follow your lab's hygiene rules for chemicals and biology.
Throw away unused material, empty vials, and contaminated supplies according to your lab's waste rules and local laws.

How long your peptide stays good — from dry powder to mixed solution.

Dry powder (unmixed): This is the most stable form. Kept sealed, frozen, and away from light, dry peptides can last 1–2 years — sometimes longer.
Refrigerated solution (2–8 °C): Once mixed, most peptides stay good for about 1–4 weeks in the fridge. Shorter or more complex sequences may break down faster.
Frozen solution (−20 °C): Split into small single-use portions before freezing. In the freezer, a mixed solution usually lasts 3–6 months. Try not to thaw and refreeze.
Freeze-thaw cycles are hard on peptides. Every time a solution warms and freezes again, the peptide bonds weaken. Pre-portion so you only thaw what you need.
When to throw it out: cloudiness, particles floating around, color change, or any smell that wasn't there before. If in doubt, discard it.
