Western blotting of Stx1 and Stx2 after nitrogen gas plasma treatment. A coverslip containing dried spots from 20 μl aliquots of a 1 μg/ml solution of Stx1 (a) and Stx2 (b) was treated with nitrogen gas plasma using BLP-TES device (1.5 kpps) for 0, 5, 15, or 30 min. The recovered samples were subjected to Western blotting using antibody recognizing the A subunit of Stx
