Registry values can differ by salt, counter-ion, hydrate, charge state or supplier representation. The lot certificate takes precedence.

1. 01

   Keep the sealed lyophilised material dry, protected from light and tightly closed.

2. 02

   For longer-term laboratory storage, -20°C is a commonly used condition for peptide reference materials; short-term requirements vary by sequence and formulation.

3. 03

   After preparing a laboratory solution, minimise time at room temperature and repeated freeze-thaw cycles. The lot-specific label, CoA and SDS take priority over general guidance.
