Antigenic Peptides Design Introduction Antigenic peptides are synthesized via short amino acid sequences derived from carefully selected native target proteins. They can be used as immunogens to produce custom antibodies and are a popular option for using full-length proteins as immunogens. Their application has grown significantly in recent years. Advantages of Using…

Chemical Synthesis of Unnatural Amino Acids Introduction Unnatural amino acids (UAAs) not exist in natural polypeptide chains, so they are considered non-proteinogenic amino acids. They are an important component in the manufacture of many drugs and expand the range of protein functions via integrating them into proteins. Based on its structure may…

RGD Peptide

Posted on
RGD Peptide Introduction RGD peptide is a synthetic peptide with the sequence GRGDSPK, which binds to integrins (receptor family of extracellular matrix proteins), thereby playing an important role in cell adhesion, migration, growth and differentiation. The RGD-sequence was originally discovered as the minimal binding epitope of fibronectin for cell attachment and…

Chemo Enzymatic Peptide Synthesis

Posted on
Chemo Enzymatic Peptide Synthesis Introduction Chemo enzymatic peptide synthesis (CEPS) is a cutting-edge technology with unique versatile engineered enzymes. It is difficult to synthesize long and complex peptides by traditional SPPS (Solid Phase Peptide Synthesis). Moreover, the chain length increases will result in high impurity levels. Furthermore, peptide recombinant expression,…

Lipopeptides and Lipoglycopeptides

Posted on
Lipopeptides and Lipoglycopeptides Introduction Lipopeptides and lipoglycopeptides are antibiotic classes with activity against gram-positive bacteria on the bacteria cell wall. Lipopeptides can create the ion-conducting channel, then cause potassium efflux and membrane depolarization, and disrupt the cell membrane finally. In order to inhibit protein synthesis and eventuate bacterial cell death…

Amide Bond Formation in Cyclization Traditional Amide Cyclization Many naturally active peptides are cyclized head-to-tail, these peptides are more resistant to hydrolysis since the absence of N- and C-terminus. Traditional coupling chemistry is used to cyclize the liner peptide precursor by amide bond formation. However, conventional head-to-tail amide formation is…
