Recombinant Proteins & Monoclonal Antibodies

Develop safe, effective and compliant biologic therapies with end-to-end analytical, bioanalytical and quality testing services from SGS – supporting recombinant proteins and monoclonal antibodies across the full development life cycle. 

Recombinant proteins and monoclonal antibodies are central to modern biologic therapy. Their structural complexity, sensitivity to manufacturing variation and rigorous regulatory expectations make robust analytical and bioanalytical support essential at every stage. For pharma and biotech organizations, ensuring product quality, safety, purity and consistency is critical to clinical success and regulatory approval.

We offer a wide range of services to support recombinant proteins and monoclonal antibodies throughout the development life cycle. Backed by a global network of laboratories and deep scientific expertise in biologics, we act as a trusted partner from early-stage research to clinical trials and commercial release.
