Higher levels of SERPINA1 were found in the plasma of non-relapsed HL patients on immunoblotting (Figure 3f), and also—though the differences were not significant—on LC-MS/MS (p = 0.21; Figure 3c), Luminex-based arrays (p = 0.27; Table S3; Figure S3a), and ELISA assays (p = 0.07; Figure S3c). This evidence concerns the gene SERPINA1 and Hodgkins lymphoma.
