Initially discovered by Gibson BW, Poulter L, Williams DH.A mass spectrometric assay for novel peptides: application to Xenopus laevis skin secretions. Peptides. 1985;6 Suppl 3:23-7. Activity was demonstrated in 1988 (see ref). Active against bacteria E. coli, S. pyogenes (10-50 ug/ml), S. aureus (50-100 ug/ml), protozoan P. caudatum, A. castellani and T. pyriformis. Rich in G, NMR structure in DPC. Magainin 2 and PGLa, isolated from the skin of the African clawed frog Xenopus laevis, show marked functional synergism (Westerhoff HV et al. 1995 Eur J Biochem 228:257-64; Rollins-Smith LA et al. 2002 Dev Comp Immunol 26:63-72; Biochemistry. 2007;46(49):14284-90). PGLa has Antibacterial, Antifungal activity. PGLa was found in skin; Stomach, African clawed frog, Xenopus laevis, Africa.

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 |
