| + | 23 | ; Lyophilised : Conditions and interval reported for the dry solid in its sealed container. A lyophilised peptide is far more stable than the same peptide in solution, because the degradation pathways that matter — [[Deamidation|deamidation]], [[Methionine oxidation|oxidation]] and [[Peptide aggregation|aggregation]] — all require water or mobility.{{r|manning}} | |
| + | 24 | ; Reconstituted : Conditions and interval after dissolution. This is the column with the weakest sourcing across the table, and the one carrying the maintenance banner: for approved products it comes from labelling, and for research compounds it is usually an extrapolation. | |
| + | 25 | ; Diluent : What the figure applies to. [[Bacteriostatic water|Bacteriostatic water]] and [[Sterile water for injection|unpreserved water]] are not interchangeable for the purpose of a storage interval, because the interval for a multi-puncture container depends on the preservative. | |
| + | 26 | ; Light : Whether photodegradation is reported as significant. Tryptophan- and tyrosine-containing sequences are the usual concern. | |
| + | 27 | ; Basis : Whether the row rests on manufacturer labelling, a published stability study, or an extrapolation. Rows marked ''extrapolated'' should not be cited as evidence about the compound named. | |
