Quality programme

Every lot leaves with paperwork you can check line by line.

We publish the certificate of analysis for the exact lot you receive — not a representative batch, not a marketing summary.

Synthesis

Solid-phase peptide synthesis in an ISO-classified suite, with in-process controls at each coupling stage.

Preparative reverse-phase HPLC to target purity, followed by lyophilization under controlled vacuum.

Every lot is sent to an unaffiliated laboratory for identity confirmation and impurity profiling.

Vials are sealed, held at −20 °C and dispatched with an in-box temperature logger you keep.

Release specification

Applied to all catalog items

Use bacteriostatic or sterile water directed down the vial wall. Do not shake — swirl until the cake fully dissolves.

Keep lyophilized material at −20 °C, desiccated and protected from light. Reconstituted solutions are typically held at 2–8 °C.

Split into single-use aliquots to avoid freeze-thaw cycling, which is the most common source of assay variance.
