Documents and storage
Every batch ships with the manufacturer's certificate of analysis. Ask for the certificate of the current batch before you order. Safety data sheet: on request. Storage: as stated on the label. As a short peptide with a basic lysine, it can carry a noticeable share of counter-ion by weight, so use the net peptide content on the certificate when making up solutions; see our storage and handling guide.
Calculated from the sequence
| Residues | 3 |
| Approximate net charge at pH 7 | about +1 (one Lys; free ends) |
| Character | Basic |
| Oxidation-prone residues | None of the easily oxidised residues (Cys, Met, Trp) |
These are estimates from the sequence, useful for planning laboratory work; the certificate of analysis reports the measured identity and purity of each batch.
