Correlation of peptide uptake with Hdm2 expression. After treatment of SJSA‐1 and HeLa cells using the indicated concentrations of the CF‐labelled CF2a peptide for 24 h, the cells were washed twice, fixed and stained with a specific antibody against the PD marker Hdm2 linked with a red fluorescent label. (A) Dose dependence of peptide uptake and (B) correlation of peptide uptake and Hdm2 expression. The figure shows the result of one representative experiment.
