Identification of p53 target genes by macroarray. Labeled cDNA from single cells or syncytia was hybridized to filters containing p53 target genes. The signal/background ratio was determined for all spots (A, with β-actin as an internal control) and the change in mRNA expression was determined as described in Materials and Methods (B).
