AI Technical Summary
Existing methods for detecting P/Q type VGCC autoantibodies suffer from insufficient sensitivity, poor specificity, unstable antigen activity, and cumbersome preparation procedures, which limit the effectiveness of early screening and diagnosis of LEMS disease.
By constructing overexpression vectors and cell lines containing the correct antigenic epitopes, we screened out important fragments that mediate autoimmune responses, designed six truncated variants covering the entire sequence, and combined them with recombinant peptides for detection, achieving highly sensitive and specific antibody detection.
It significantly improves the detection accuracy of P/Q type VGCC autoantibodies, providing a reliable basis for early screening, diagnosis and disease monitoring of LEMS, improving the entire diagnosis and treatment process, and enhancing the sensitivity and specificity of the test.
