PAC has emerged as indispensable tools in the field of biomedical research, offering multifaceted advantages such as targeted drug delivery, augmented therapeutic effectiveness, and enhanced diagnostic capabilities. The convergence of antibodies and peptides within PAC has revolutionized the landscape of precision medicine, propelling the field toward personalized and more efficacious treatment strategies.

Our Services

Our company offers comprehensive a range of services for peptide antibody conjugation, ensuring the quality, stability, and efficacy of these conjugates. Through our state-of-the-art facilities and experienced team of scientists, we provide analytical techniques and assays to evaluate the properties and performance of PAC.

Peptide Design and Synthesis (Optional)

Through careful analysis of target antigens, we can engineer peptide sequences that possess optimal binding affinity and specificity.

Optional Gene Therapies

The success of PAC hinges upon the appropriate selection of antibodies with high binding affinity towards the target antigen. Our company offers a vast array of monoclonal and polyclonal antibodies for different applications.

Peptide Antibody Conjugation

We can provide cutting-edge conjugation methodologies, such as site-specific conjugation, to ensure a stable and homogeneous PAC product and preserve the native activity of the antibody and peptide.

Characterization of PAC

Comprehensive biochemical characterization includes:

  • Conjugation efficiency
  • Drug-to-antibody ratio (DAR)
  • Stability
  • The binding affinity of the PAC towards the target antigen

We are committed to providing biology experts with tailored PAC services to advance your research and rare disease drug development goals as efficiently and effectively as possible. If you are interested in our services, please feel free to contact us for more details and quotation information of related services.
