A sub-line with increased metastatic ability was previously isolated from an established human colonic carcinoma cell line. The separation and characterization of the isoenzymes of N-acetyl-β-D-hexosaminidase from each cell line are reported. The parental cell line contained A and B isoenzymes. The sub-line lacked the A-isoenzyme activity and contained an atypical B isoenzyme that was thermolabile, susceptible to alkylation and of lower molecular weight.
