Figure 2: Effects of Ptx and roscovitine and combined effect of roscovitine + Ptx on activation and expression of proteins involved in apoptosis of KTC-2 cells. (a) Western blotting study. (b) Quantification of WB results. Data are mean of 4 OD measurements of one blot by scanning software ± SD value (error of scanning). CDKI: Cdk inhibitor, roscovitine; IOD: integrated OD, MOD: maximal OD of the bands.
