Royobiotech Co.,Ltd has a track record for synthesizing biologically active long peptides (> 150 amino acids in length) with the purity and speed previously only possible with shorter peptides. Producing these long peptides was previously performed using recombinant DNA methods. However, due to likelihood of endotoxin contamination, these methods can be problematic. Chemical peptide synthesis offers lower toxicity in downstream applications. Custom long peptide synthesis is carried out using optimal ligation and fragment condensation methods.
All Royobiotech's specialty peptides are provided in the highest purity (>95%), with a full range of analyses including LC-MS (trap and/or quad), MALDI-MS, HPLC, AAA, NMR, CE, as well as peptide content determination to confirm the identity and demonstrate the high quality of our custom long peptides.
