Why is solid phase peptide synthesis limited to 70 amino acids?
WebEssential protocols for the synthesis of fully deprotected peptides are presented including resin handling, coupling, capping, Fmoc-deprotection, final cleavage and disulfide bridge … The established method for the production of synthetic peptides in the lab is known as solid phase peptide synthesis (SPPS). Pioneered by Robert Bruce Merrifield, SPPS allows the rapid assembly of a peptide chain through successive reactions of amino acid derivatives on a macroscopically insoluble solvent-swollen beaded resin support. WebAs a result, we recommend increasing the delivery of the Cap A/B mix on Expedites by 50% (going from 8 to 12 pulses) as well as increasing the time interval by 50% (going from 15 to 22 seconds). The most efficient capping reagent though is 6.5% DMAP solution used for Cap B. When this is used on an ABI 394, the capping efficiency jumps to >99%. cleveland used bookstores
