“…On the other hand, addition of exogenous neuraminidase from Clostridium perfringens stimulated cell growth in different cell lines. Thus, the attempts to downregulate cellular neuraminidase activity should pay respect to possible growth stimulating functions of this enzyme (Cantz et al, 1993;Sweeley, 1993;. Cost-and/or time-consuming analytical methods of recombinant proteins, e.g., high performance anion exchange chromatography with pulsed amperometric detection (Townsend et al, 1989), enzyme array (Edge et al, Figure 5.…”
