Effects of Lipidation on a Short Antimicrobial Peptide

H. Bauke Albada, et al. have just reported (ACS Med. Chem. Lett., Just Accepted Manuscript DOI: 10.1021/ml300148v) that adding lipids attached to the sidechain of a lysine residue at the N- or C-terminal of the short antimicrobial peptide (Arg-Trp)3 significantly...

Self-assembled Peptide Nanofibers

K. Tomizaki et al. recently published a report (Langmuir, Article ASAP, DOI: 10.1021/la301745x) about two short peptides that self-assemble into nanofibers.  They used the nanofibers as templates for forming and aligning ZnO particles at room temperature.   These...

Slow Gradient HPLC for Peptide Purification

Harris, Lee and Brimble reported in the J. Pept. Sci. (J. Pept. Sci. 2012, 18(9); 549-55.)  that they could purify hundreds of milligrams of peptide on a semi-preparative column in a single step by using a slow gradient of 0.1%B per minute. Their results are...

Cysteine Racemization

JH Park, et al. reported in J Pept Sci. 2012 ;18(7):442-8 that in the synthesis of Protoxin II, they saw up to 50% racemization of Cys during coupling when they used N-methylmorpholine.  They could significantly reduce racemization if they used 2,4,6-collidine in...
