AI Technical Summary

Technical Problem

Existing ApoE4-specific antibodies have low specificity in clinical testing and cannot meet the needs of accurate diagnosis, especially in the auxiliary diagnosis of Alzheimer's disease. Existing detection methods such as chemiluminescent immunoassay and immunochromatography are lacking in specificity and sensitivity.

Method used

An antibody against ApoE4 or its antigen-binding fragment was designed and prepared. By designing a complementarity-determining region (CDR) and a framework region (FR) with a specific combination of amino acid sequences, the binding specificity and affinity with ApoE4 were improved. This antibody can be used in detection methods such as immunochromatography, enzyme-linked immunosorbent assay (ELISA), and chemiluminescence immunoassay to enhance the sensitivity and specificity of detection.

Benefits of technology

This technology enables efficient qualitative or quantitative detection of ApoE4, improving the specificity and sensitivity of the detection and meeting the precision requirements of clinical diagnosis.
