Two-dimensional gel electrophoresis (2DE) is an important tool for investigating the complexity of snake venom proteomes. Apart from applications based on whole proteome analysis, we suggest that 2DE can be used as an assay to guide the progress of protein purification. The aim of this study was to prove the feasibility of this concept by using it to purify rhodocetin from Calloselasma rhodostoma venom. Rhodocetin (α subunit) spot on the 2DE profile of C. rhodostoma venom was first identified and confirmed by mass spectrometry, with a molecular mass of 16 kDa and calculated pI of 5.16. Rhodocetin was subsequently purified by successive anion-exchange and gel filtration chromatography. Every peak from both chromatography profiles was collected and tested on... |
