Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2 mL bacteriostatic water to the lyophilized vial and swirl gently. Dissolves within 1 minute.
How should this peptide be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks.
What purity is this QSC compound and how is it verified?
Livagen targets both liver and haematopoietic tissues, making it distinctive among Khavinson bioregulators. Research by the St. Petersburg institute suggests it promotes chromatin decondensation, activating age-silenced genes in these tissues.
