Tissue Cross-Reactivity Evaluation

Tissue cross-reactivity (TCR) evaluation is crucial to the safety evaluation of preclinical monoclonal antibody drugs. Our company employs talented and highly trained scientists who focus on every aspect of rare disease drug development and research. Our extensive experience in providing rare disease therapy solutions allows us to provide you with customized tissue cross-reactivity evaluation services, and we can quickly respond to the changing needs of your rare disease research projects.

Introduction to Tissue Cross-Reactivity Evaluation

Tissue cross-reactivity (TCR) is essential to the development of monoclonal antibodies and other related biologics, primarily to identify off-target binding, but may also be used to identify previously unknown target binding sites. Monoclonal antibodies usually have specific immune properties. There are antigenic determinants that are the same or similar to specific target sites in normal human tissues and are prone to adverse reactions. Therefore, TCR evaluation is an important method to detect the safety of monoclonal antibody drugs. It provides an important reference for drug clinical toxicity prediction and monitoring.

Applications of Tissue Cross-Reactivity Evaluation

  • Determination of antibody binding to targeted epitopes.
  • Determination of antibody binding to non-targeted antigens.
  • Determination of relevant animal species for preclinical safety testing.
  • Prediction of target organ toxicity of drugs.
