Research Guides
Working with research peptides
Reference material for the practical side of the catalogue — preparing a vial, storing it properly, and reading the paperwork that came with it. Written for laboratory work, not for administration.
01
Reconstitution & diluent
What happens when a lyophilised vial meets bacteriostatic water — choosing a diluent volume, the concentration maths, and the mistakes that cost a vial.

02
Storage & aseptic handling
Receiving a cold-chain parcel, storage temperatures before and after reconstitution, aliquoting to avoid freeze–thaw cycles, and clean technique at the bench.

03
Lab testing & reading a COA
What HPLC and LC-MS each actually measure, how to read a chromatogram, and how to tell a real Certificate of Analysis from a fabricated one.

04
Solubility & difficult compounds
The compounds bacteriostatic water will not dissolve — isoelectric point and hydrophobicity, acidic and DMSO stocks, surface adsorption, and metal cofactors that a buffer can strip.

05
What purity actually means
Why a 99% pure peptide is not 99% peptide by mass: HPLC area percentage against net peptide content, TFA counterion, residual water, and when the difference matters.
