    Rich in P. Active against A. tumefaciens Gembloux A, E. salicis NCPPB 2530, E. coli NCTC 9001 (MIC 25-50 ug/ml), E. coli NCTC 9001*, E. coli K514 (MIC 10-25 ug/ml), P. syringae pv. tomamta NCPPB 1105 (MIC 25-50, X. campestris pv. vesicatoria LMG 905 (MIC 5-10 ug/ml), and Gram-positive bacteria B. megaterium OMB 1551 (MIC 10-25 ug/ml) and M. luteus (M. lysodeikticus) LMG 4050 (MIC 10-25 ug/ml). Thus, the highest observed specific activity of the peptide was against an apidaecin-resistant Xanthomonas strain. Relish regulates expression of antimicrobial peptide genes in the honeybee, Apis mellifera, shown by RNA interference (Insect Mol Biol. 2007 Dec;16(6):753-9). APD Updated 10/2008. name corrected 5/2014 GW. Abaecin has Antibacterial activity. Abaecin was found in honeybee, Apis mellifera L..
  • Storage Guidelines
    Ideally Abaecin peptide should be stored in a freezer at or below -9C. Abaecin peptide should be refrigerated after reconstitution. For more details, please refer to the manual:Handling and Storage of Synthetic Peptides

  • About TFA salt

    Trifluoroacetic acid (TFA) is a strong acid, which is commonly used to cleave synthesized peptides from solid-phase resins and is also used to improve HPLC performance in the peptide purification step. By default, custom peptides are delivered as lyophilized TFA salts, and can contain as much as 10-45% TFA.

    TFA in custom peptides can cause inexplicable discrepancies in subsequent assay data. For instance, TFA in nM concentrations has been shown to interfere with cellular assays, inhibiting cellular proliferation in some instances, and increasing cell viability in others . It has also been found to be an unintended allosteric modulator of the glycine receptor, GlyR.

    TFA Removal Service is recommended for:

    • Peptides that will be used in cellular assays
    • Peptides that will be used as APIs or in manufactured products
    • For hydrophilic peptides containing numerous basic residues
