Recombinant Escherichia coli Colicin-Ia (cia) , partial

• CAS Number:

  9000-83-3

• Gene Name:

  cia

• UniProt:

  P06716

• Expression Region:

  282-385aa

• Organism:

  Escherichia coli

• Target Sequence:

  KNTPDGKTIVSPEKFPGRSSTNHSIVVSGDPRFAGTIKITTSAVIDNRANLNYLLSHSGLDYKRNILNDRNPVVTEDVEGDKKIYNAEVAEWDKLRQRLLDARN

• Tag:

  N-terminal 6xHis-tagged

• Source:

  E.coli

• Field of Research:

  Others

• Assay Type:

  Developed Protein

• 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.

• Purity:

  Greater than 85% as determined by SDS-PAGE.

• Activity:

  Not Test

• Length:

  Partial

• Form:

  Liquid or Lyophilized powder

• Buffer:

  If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Molecular Weight:

  15.7 kDa

• Storage Conditions:

  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
