A 10 mg Epitalon vial reconstituted with 2 mL gives 5 mg/mL. Measuring 0.100 mL gives 500 mcg per portion — about 20 portions from the vial.

Choosing a diluent for Epitalon

Extremely water-soluble and effectively instantaneous to dissolve. With only four residues, two of them acidic, there is no hydrophobic character and no conformational complexity whatsoever. If an Epitalon vial does not clear immediately, the problem is the vial, not the chemistry.

PrimarySterile or bacteriostatic water
Alternative 1Saline
Alternative 2Phosphate-buffered saline

Handling notes for Epitalon

  • Do not over-engineer storage for this compound — refrigeration and a sound seal are genuinely sufficient.
  • Avoid prolonged storage of reconstituted solution, since Asp-Gly isomerisation is slow but cumulative.
  • Verify the analytical method behind any purity figure, as short polar peptides are easy to under-resolve.

After reconstitution

StorageRefrigerate at 2–8 °C. No methionine, cysteine, or tryptophan — light protection is not the priority it is for other compounds here.
Working windowCommonly worked with for 3–4 weeks at 2–8 °C.
Freeze–thawHighly tolerant. A four-residue peptide has essentially no structure to disrupt, making this one of the more freeze-tolerant compounds in the catalogue.
