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. The sequence contains two methionines and a tryptophan, which oxidise easily, so keep the vial tightly closed and cold; our storage and handling guide explains why.
Calculated from the sequence
| Residues | 16 |
| Approximate net charge at pH 7 | about +3 (three Arg and one Lys against one Glu; free ends) |
| Character | Basic overall |
| Oxidation-prone residues | Two methionines and one tryptophan |
These are estimates from the sequence, useful for planning laboratory work; the certificate of analysis reports the measured identity and purity of each batch.
