The omniPAGE VS30 maxi-plus large format vertical has been designed as a convenient unit for second-dimension PAGE following first-dimension isoelectric focusing using the CSL-IEF. An active gel width of 26cm easily accommodates IPG strips up to 24cm in length, the longest available commercially, while an extended gel height of 22cm maximises separation distance and resolution of proteins similar in size or isoelectric point (pI). In combination with the CSL-IEF, the VS30DSYS provides a complete 2-D electrophoresis system which utilises the advanced features of the omniPAGE range to produce a unit that is both easy to use and consistent in generating reproducible results.
Rapid set-up cooling retains resolution in extended separations and also conserves buffer volume without affecting run quality. A maximum of four 1-mm-thick gels may be resolved per run, using notched glass plates with 1mm bonded spacers; and a comprehensive range of accessories facilitate easy interchange between 2-D and standard vertical electrophoresis techniques. Different types of 2-D comb offer a wide degree of versatility in sample selection and gel set-up.
