Fig 1: ELISA analyses of tissue (A and B) and serum (C and D) proteins in BTG, PTCa and PTCb patients.ELISA was performed using antihuman A1AT, HSP 70 and AHSG as primary antibodies. Single (*) asterisk denotes a p < 0.05 when PTCa (n = 8) and PTCb (n = 6) were compared to BTG (n = 20). Assay was performed in duplicate and data are presented as mean ± standard error of the mean (SEM) from biological replicates.
