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...
