Research Handbook
Reference material for handling, reconstituting, storing, and documenting research peptides. For laboratory use only.
Reconstitution
Reconstitute lyophilized peptide with bacteriostatic or sterile water. Add the solvent slowly down the vial wall — do not spray directly onto the powder. Swirl gently; never shake. Allow to dissolve fully before use.
Dilution calculator
On a U-100 insulin syringe, 100 units = 1 ml. You enter your own target — this is a calculation, not a dose recommendation.
Storage & cold chain
Store lyophilized vials at -20°C for long-term storage. Once reconstituted, keep refrigerated at 2–8°C and use within the documented window. Avoid repeated freeze-thaw cycles. Protect from light.
Sterile handling
Wipe the vial septum with an alcohol swab before each draw. Use a fresh sterile needle each time. Work in a clean area and avoid touching the needle or septum.
How to read a COA
A Certificate of Analysis documents identity and purity for a specific batch. Check the compound name and batch/lot number match your vial, the HPLC purity figure (typically ≥99%), the mass-spec identity confirmation, and the test date.
Dosing & usage
Dosing and usage guidance for these research compounds is provided by the client and will appear here once supplied.
Glossary
- HPLC
- High-Performance Liquid Chromatography; the method used to quantify purity.
- COA
- Certificate of Analysis; per-batch documentation of identity and purity.
- BAC water
- Bacteriostatic water; sterile water with 0.9% benzyl alcohol used to reconstitute peptides.
- Lyophilized
- freeze-dried into a stable powder for storage and shipping.
- Reconstitution
- dissolving lyophilized powder into solution before use.
