Storage & Reconstitution Recommendations lyophilized Charybdotoxin can be kept at 4 °C. It should be reconstituted in saline solution (about 150 mM salt is recommended); use only glass or pyrex but not plastic containers‚ as Charybdotoxin has a tendency to stick to different kinds of materials at low salt concentration. Though exceptionnally stable (3)‚ the unused peptide should then be relyophilized or stored at -20 °C.
