Our results thus identified 10 distinct proteins including keratin type-I cytoskeletal 10 (spot, 1), hemopexin (spot, 2 and 3), haptoglobin (spot, 4 and 5), fibrinogen gamma chain (spot, 6), serotransferrin (spot, 7), alpha1antitrypsin (spot, 8-11), fibrinogen alpha chain (spot, 12 and 13), keratin type- I cytoskeletal 10 (spot, 14,15), apo-lipoprotein A-I (spot, 16), transthyretin (spot, 17), talin-1 (spot, 18), and alpha-2HS glycoprotein (spot, 19) from CAD plasma (Table 2). Here, SERPINA1 is linked to coronary artery disorder.
