• UniProt:

  B6S2X2

• Expression Region:

  162-191aa

• Organism:

  Ophiophagus hannah (King cobra) (Naja hannah)

• Target Sequence:

  KFFKKLKNSVKKRAKKFFKKPRVIGVSIPF

• Tag:

  N-terminal 6xHis-SUMO-tagged

• Type:

  Developed Protein

• Source:

  E.coli

• Field of Research:

  Others

• Relevance:

  Potent antimicrobial peptide against Gram-negative (MIC=0.25 ug/ml against E.coli ATCC 25922, MIC=0.5 ug/ml against P.aeruginosa) and Gram-positive bacteria (MIC=64 ug/ml against E.faecalis, MIC=64 ug/ml against S.aureus) . Adopts an amphipathic alpha helical conformation, that may allow to partition into the target membrane. Low hemolytic activities have been observed on mammalian cells.

• Endotoxin:

  Not test

• Purity:

  Greater than 95% as determined by SDS-PAGE.

• Activity:

  Not Test

• 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Molecular Weight:

  21.8 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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
