Reference material is only as good as the way it is kept. The following applies to laboratory research materials in their supplied form.
| Lyophilised material, unopened | -20 °C, desiccated and protected from light |
|---|---|
| Short-term handling | 2–8 °C for periods measured in days, not weeks |
| In transit | Brief ambient excursion is tolerated by lyophilised material; refrigerate on arrival |
| Reconstituted solution | 2–8 °C, protected from light; avoid repeated freeze-thaw cycling |
| Solvent selection | Bacteriostatic water suits most sequences; hydrophobic and highly basic sequences may require dilute acetic acid to achieve a clear solution |
| Aliquoting | Divide into single-use volumes before freezing to avoid cycling the whole stock |
