Aptamer's properties for PTEN protein detection.

Properties measured in the aptamers derived from peptides (PTENz7 and PTENz14) and cloned aptamers derived from the recombinant protein GST-PTEN (Clone 3, Clone 4, Clone 5, Clone 6, Clone 7, Clone 8 and Clone 9). The columns: western blot, histology and cellular localization show the performance of each aptamer for the corresponding assay and their subcellular localization. Aptamers PTENz7 and PTENz14 are recognized as the best choice considering their ability to recognize the native protein PTEN, their well-defined localization and different manifestations in subcellular regions.
