Purification of NSR30. (a) Chromatogram representing the purification of NSR30 by size-exclusion chromatography. (b) 15% SDS–PAGE showing the purified NSR30 fractions. Lane 1 contains PageRuler Unstained Protein Ladder (labelled in kDa) and lanes 2–8 contain the purified NSR30 fractions at 35 kDa. The lower 30 kDa band also arises from NSR30, as verified by mass spectrometry, and is likely to be a degradation product. a, b and c refer to the protein standards BSA (molecular weight 67 kDa), β-lactoalbumin (35 kDa) and cytochrome c (12.7 kDa), respectively.
