The protein expression of XTLY-I by Western blot analysis. (A): Detection of XTLY-I protein expression in different groups by Western blot analysis. Band of XTLY-I (120 kDa.) was identified in different cells. Lane 1: SACC-M cells; lane 2: SACC-M-HK cells; lane 3: SACC-M-WJ4 cells. Fig. 4 (B): The comparison of XTLY-I protein expression in different groups. Value (XTLY/GAPDH) means the band integrated opitical density (IOD) ratio of XTLY and GAPDH.
