Fig. 2. Identification of human SA-β-gal from E. coli β-gal using species-selective chemical probe. (a) Selective enzyme-triggered hydrolysis of species-selective probe KSL11 by SA-β-gal but not E. coli β-gal. (b) Schematic representation of the recognition process of SA-β-gal and E. coli β-gal with the traditional type of probe and KSL11.
