The AA sequence of Cecropin A2 from Drosophila melanogaster is identical to the major cecropin (Sarcotoxin IA) from Sarcophaga peregrina. The peptide is induced via the IMD pathway. The peptide contains two amphipathic alpha helices: helix I (3-23) and helix II (28-38), with a hinge region (G24-I27) (NMR: Iwai H et al., Eur. J. Biochem.1993; 217: 639-644). Transgenic plants: expression of this peptide in tobacco confers partial resitance to pathogens (Montesinos E 2007 FEMS MIcrobiol Lett 270: 1-11). Found in multiple species. Sarcotoxin IA has Antibacterial activity. Sarcotoxin IA was found in Flesh fly, Sarcophaga peregrina; or fruit fly, Drosophila melanogaster.

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 |
