"Peptides LL-37 (LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES), a scrambled LL-37, sLL-37 (RSLEGTDRFPFVRLKNSRKLEFKDIKGIKREQFVKIL) and IG-19 (IGKEFKRIVQRIKDFLRNL-NH2) were obtained from CPC Scientific (Sunnyvale, CA). The peptides were re-suspended in endotoxin-free water and stored at −20° until needed."

"..folded HD5 was generated from a synthesized 80% pure linear peptide (CPC Scientific, Sunnyvale, CA) by thiol disulfide reshuffling overnight at room temperature in the presence of 3 mM reduced and 0.3 mM oxidized glutathione, 2 M guanidine hydrochloride, and 0.25 M sodium bicarbonate, pH 8.3, at a peptide concentration of 0.25 mg/ml [..] All α-defensins were quantified by UV absorbance at 280 nm using calculated molar extinction coefficients (18)."

"The peptides were synthesized as 4-branch MAPS peptides that include a SGGRGG spacer at the C-terminal residue to distance the gp41 sequence from the MAPS (CPC Scientific; San Jose, CA)."

"(R/K)-RMAD-4 [rhesus myeloid α-defensin 4] [(R1/2/5/7/10/13/14/26/33K)-RMAD-462-94] was custom synthesized by CPC Scientific, Inc. (San Jose, CA) and refolded as described previously…"
