What is coupling reagents?

luka is a all-around supplier of the able superior coupling reagents, accessible from analysis to all-embracing quantities. We focus on a ample array of able peptide coupling reagents, carbodiimides and additives for accomplishing fast, efficient, careful and racemization-free amidation in a advanced array of bread-and-butter systems.

In principle, the acutely simple accumulation of a peptide band can be able application all the procedures accessible in amoebic allure for the amalgam of carboxylic acerbic amides. However, due to the attendance of assorted anatomic groups in accustomed and aberrant amino acids and decidedly the claim for abounding assimilation of chiral integrity, the coupling of amino acids and peptides beneath balmy altitude can be challenging. A deluge of coupling reagents has been developed superseding anniversary added in ability and adequacy for specific applications (e.g., solid-phase peptide amalgam or fragment condensation).

All coupling methods accept the aforementioned acknowledgment assumption in common: afterwards activation of the carboxy accumulation of the aboriginal amino acid, the additional amino acerbic can anatomy the peptide band by a nucleophilic advance of its amino group. In adjustment to anticipate amoral peptide band accumulation the amino accumulation of the aboriginal amino acerbic and all anatomic ancillary alternation groups charge to be reversibly blocked. Repeated de-blocking, activation, and coupling body the peptide to its adapted final sequence.
