Effect of two kinds of ILs on CA conversion. CA conversion ratios when ASP cells are pre-incubated with 0.5 % (v/v) two kinds of ILs and without ILs. The ILs-treated ASP cells were washed with PBS for three times and resusupended in the same buffer, respectively. The conversion ratios of CA were determined by HPLC analysis. a CA conversion in presence of [PrMIm]BF₄ or pretreatment. b CA conversion in presence of [PrMIm]PF₆ or pretreatment. Standard deviations are indicated by error bars or are within each symbol
