Chemical ligation yield
WebAn advancement of the hydrazide mediated NCL is noticeable with NCL yields of 39% ( Zheng et al., 2016; Tang et al., 2024 ). However, this method is hampered by impossible incorporation of removable C-terminal solubilizing tag to the hydrazide moiety. WebMay 24, 2006 · Native chemical ligation of unprotected peptide segments involves reaction between a peptide-alpha-thioester and a cysteine-peptide, to yield a product with a native amide bond at the ligation site. Peptide-alpha-thioalkyl esters are commonly used because of their ease of preparation.
