Frequently Asked Questions
Why is lyophilization essential for synthetic research peptides?
Lyophilization (freeze-drying) removes water through sublimation under vacuum at low temperatures. This preserves the peptide tertiary conformation and prevents hydrolytic degradation, allowing the compound to remain stable for years at -20°C.
How do I identify a high-quality lyophilized peptide cake?
A high-grade lyophilized peptide appears as a solid, uniform white or pale cake adhering to the base of the glass vial under vacuum. Fragmented powders or discolored residues may indicate moisture exposure or improper sublimation.
What is the correct protocol for reconstituting lyophilized peptides?
Equalize the vial to room temperature before puncture. Inject bacteriostatic water slowly along the inner vial wall to avoid mechanical shearing. Swirl gently until dissolved. Never agitate or vortex vigorously.
