Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids (typically 2–50) that act as signaling molecules in biological systems. They are widely studied for their role in cellular processes, regeneration, metabolism, and immune modulation. All EndaG1 peptides are intended solely for laboratory research use.

Question 2

What purity level do you provide?

Accepted Answer

All EndaG1 peptides are ≥ 98% pure by HPLC (typically 99%+). Each batch is independently verified via HPLC and mass spectrometry. A Certificate of Analysis (COA) is available for every batch on request.

Question 3

How should peptides be stored?

Accepted Answer

Lyophilized peptides should be stored in a cool, dry, dark environment (ideally at 2–8°C or frozen for long-term storage). Once reconstituted with bacteriostatic water, store refrigerated (2–8°C) and use within the timeframe indicated on the product's COA. Avoid repeated freeze-thaw cycles.

Question 4

How do I reconstitute a lyophilized peptide?

Accepted Answer

Standard reconstitution uses sterile bacteriostatic water (0.9% benzyl alcohol) added slowly along the vial wall — do not inject directly onto the lyophilized powder. Swirl gently until fully dissolved. Do not shake vigorously. Reconstitution volume depends on your target concentration; consult the COA for guidance.
