Characterize and optimize therapeutic peptide programs with Element’s deep bench of advanced technology and understanding of biological chemistry while generating characterization data required to meet crucial regulatory milestones.

Peptide therapies, coupled with advances in chemical synthesis, have opened new doors to new discovery opportunities, given their unique blend of properties, simple late-stage production and low manufacturing costs. Therapeutic peptides play a critical role as signaling molecules and hormones, and they continue to be valuable for interventions that closely mimic native interactions.

Although the barriers to entry are lesser, as complex biomanufacturing is not required, therapeutic peptides pose a number of challenges. Naturally occurring peptides can suffer from low bioavailability, chemical and physical instability, poor membrane permeability, and fast metabolism and elimination. Additionally, potentially hazardous residual components can be produced when peptides are manufactured through chemical synthesis, requiring identification, control and mitigation strategies to be in place before production can be scaled. Overcome these hurdles and expedite path-to-market with Element’s comprehensive peptide analysis suite of services, which have been built to maximize efficiencies, with a focus on peptide stability and efficacy.

Peptide analysis methods and capabilities

Peptides have unique properties and analytical needs and can be filed with health agencies as a small molecule, with small protein molecular characteristics. Strengthen your regulatory submission strategy with Element’s expert regulatory and scientific guidance regarding the best approach for each program, along with the assays, tools and techniques needed to deliver highly reliable results.
