Test of the ScPIP2–1 trans-activation assay. The media were added with X-Gal (5-bromo-4-chloro-3-indoxyl-D-galactopyranoside). 10− 1, 10− 2, 10− 3 and 10− 4 represent the sample concentrations diluted ten-fold, hundred-fold, thousand-fold and ten thousand-fold, respectively. SD/−Leu, the synthetic dropout medium without leucine; SD/−Leu/−Trp, the synthetic dropout medium without leucine and tryptophan; SD/−Ade/−His/−Leu/−Trp, the synthetic dropout medium without adenine, histidine, leucine and tryptophan
