| 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 | The major porin in this organism, forms a water-filled channel which favors the permeation of cations, amino acids, iron Fe3+ and less efficiently phosphate. Does not transport Fe-ExoMS, the predominant siderophore. Plays a role in transport of beta-lactamase and hydrophilic fluoroquinolone antibiotics such as norfloxacin as well as chloramphenicol. There are about 2400 porins in wild-type, 800 in an mspA deletion and 150 in a double mspA-mspC deletion. Different conductance values with maxima at 2.3 and 4.6 nanosiemens might be caused by a simultaneous reconstitution of MspA channels into the membrane or by the existence of different MspA conformations. |
