    Snippet: (FAFLAAIPSILSAL) were identified from the E. validus venom gland cDNA library and chemically synthesized. The peptides synthesized in this study were prepared by ChinaPeptides Company, a leading supplier of synthetic peptides in China. Briefly, the peptides were synthesized using solid-phase synthesis and C-terminal amidation in a standardized process. Fmoc-rink resin was used as the synthesis resin by Fmoc strategy.

    Document: (FAFLAAIPSILSAL) were identified from the E. validus venom gland cDNA library and chemically synthesized. The peptides synthesized in this study were prepared by ChinaPeptides Company, a leading supplier of synthetic peptides in China. Briefly, the peptides were synthesized using solid-phase synthesis and C-terminal amidation in a standardized process. Fmoc-rink resin was used as the synthesis resin by Fmoc strategy. Piperidine was used for deprotecting, and HOBt/HBTU was used for coupling. The finished peptides were cleaved from the resin using trifluoroacetic acid (TFA), precipitated with ether and subjected to purification by reverse-phase HPLC on a C-18 hydrophobic resin (Elite-HPLC) in 0.1% TFA using an acetonitrile gradient. The purity of the final material was verified by reverse-phase HPLC, and the mass of the peptide was determined by mass spectrometry (Voyager-DESTR; Applied Biosystems). All peptides had purities of 95% or greater.
