Effects of mac25 recombinant protein on the growth of cultured tumor cells.
105 cells of each cell line were inoculated and the numbers of cells were counted after 1 and 3 days. Left panels show the total cell numbers against culture day. Bars indicate standard deviations. Right panels show changes in fractions of viable cells plotted against the concentration of mac25 recombinant protein. Upper, middle and lower panels show the results for Saos-2 cells, HeLa cells and P19 cells, respectively.
