| Form | Liquid or Lyophilization |
| Buffer | The default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol if the delivery form is liquid. The lyophilization buffer is Tris/PBS-based buffer, 6% Trehalose, pH 8.0 if the delivery form is lyophilized powder. Please contact us if you have any special requirment. |
| Reconstitution | Please reconstitute protein in deionized sterile water and we recommend that briefly centrifuge thevial prior to opening the vial .We recommend aliquot for long-term storage at -20℃/-80℃. |
Background
| Relevance | This colicin is a channel-forming colicin. This class of transmembrane toxins depolarize the cytoplasmic membrane, leading to dissipation of cellular energy. Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria. |
| Involvement in Disease | |
| Subcellular Location | Cell membrane, Multi-pass membrane protein |
| Protein Families | Channel forming colicin family |
| Tissue Specificity | cea |
