Description
Active against Gram-positive S. aureus ATCC25923, E. faecalis ATCC29212, S. aureus IS 10# (MIC 2.5-5 uM), S. aureus IS 37#, Gram-negative E. coli ATCC25922, E. cloacae ATCC13047, K. pneumonia ATCC700603 (MIC 10-20 uM), B. pyocyaneus CMCCB1010 (MIC 40 uM), P. aeruginosa ATCC27853, B. dysenteriae (MIC 5 uM), E. coli IS 37# (MIC 10 uM), E. coli IS 117# (MIC 40 uM), E. coli IS 218#, P. aeruginosa IS 350# (MIC 20 uM), K. pneumonia IS 59# (MIC 10 uM), fungi C. albicans ATCC2002, C. albicans ATCC90028 (MIC 10 uM), and C. parapsilosis ATCC22019 (MIC 40 uM) (Yang et al., 2013). Mastoparan M made in all D-amino acids showed 2-fold higher antibacterial activity than L-mastoparan M (Li ML et al 2000 Int J Antimicrob Agents. 13(3):203-8). The same peptide is also expressed in Vespa magnifica (Xu X et al, 2006) and Vespa tropica (Yang et al., 2013). Found in multiple species. Updated 3/2014; 4/2014 Mastoparan M has Antimicrobial activity. The source of Mastoparan M is Hornet Vespa mandarinia ; venom gland, the social wasp Vespa tropica; wasp venom, Vespa magnifica.

About TFA salt
Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.
Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.
Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.
In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
