The qualitative discrimination of SjAb with ECISA.
(A) Cyclic voltammograms (CV) curves for the detection of SjAb in PBST(short dashed line), negative reference serum (long dashed line)and positive reference serum (solid line) using ECISA. (B) Amperometric(I-t) curves for the detection of SjAb in PBST(short dashed line) negative reference serum (long dashed line)and positive reference serum (solid line) using ECISA.
