In the study by Woo et al. [30], the anti-FOXP3 Ab20034 (clone 236A/ E7) antibody which was used in the current study was compared with the anti-FOXP3 Ab22510 antibody, and the authors concluded that more specific staining was obtained with Ab20034 in cervical intraepithelial neoplasia tissue sections. This evidence concerns the gene FOXP3 and cervical intraepithelial neoplasia.
