Therapeutic Single Domain Antibody Development for Pancreatic Cancer
Single domain antibodies (sdAbs), derived from camelid antibodies, offer unique advantages such as smaller size, higher stability, and better tissue penetration compared to conventional antibodies. Alfa Cytology provides preclinical solutions for discovery and optimization of sdAbs, addressing the critical need for effective pancreatic cancer therapies. Our service includes comprehensive support from antigen identification and antibody generation to functional assays and preclinical validation.
Single Domain Antibody for Pancreatic Cancer Therapy
Therapeutic single domain antibodies, also known as VHHs or single-domain antibodies(sdAbs), are a novel class of antibodies derived from heavy-chain-only antibodies found in camelids. These antibodies are exceptionally small, typically around 12-15 kDa, which allows for superior tissue penetration and targeting of tumor microenvironments that are often inaccessible to conventional antibodies.

Single domain antibodies can be easily engineered and humanized, facilitating their translation from preclinical studies to potential clinical applications. In pancreatic cancer research, these antibodies play a crucial role in the identification and validation of novel therapeutic targets, the development of targeted therapies, and the enhancement of diagnostic accuracy.
Advantages of Therapeutic Single Domain Antibody
- Deep Tumor Penetration: Nanoscale dimensions for effective tumor and the blood-brain barrier (BBB) penetration.
- High Affinity and Specificity: High target affinity with minimal off-target effects.
- Robustness and Refolding Capacity: High resilience and refolding ability after denaturation.
- Thermal and Environmental Tolerance: Stability under extreme temperatures, pressures, and pH levels.
- Cost-effective Production: Inexpensive and straightforward microbial synthesis.
