Reconstitution & Storage for Research Peptides

Handling lyophilized peptides

Lyophilized (freeze-dried) peptides are shelf-stable for months when kept cold and dry. Once reconstituted, the clock starts.

Reconstitution

Use bacteriostatic water for multi-use vials. The 0.9% benzyl alcohol inhibits microbial growth across repeated draws. Add the diluent slowly down the vial wall; never spray directly onto the powder. Swirl, don't shake.

Dilution math

Concentration = peptide mass ÷ diluent volume. Reconstituting a 10mg vial with 2mL yields 5mg/mL. Always document the diluent volume on the vial label so the concentration is reproducible.

Storage

Avoid repeated freeze-thaw cycles. Protect from light. For laboratory research use only.
