Identification of p53 and Its Isoforms in Human Breast Carcinoma Cells

Figure 4

p53 immunostaining in malignant breast epithelial cells. Almost all neoplastic cell nuclei reveal strong accumulation of the p53 protein. p53-positive cells have red nuclei and a green staining underlines nuclei of unlabelled cells (frozen section, alkaline phosphatase antialkaline phosphatase—APAAP—technique, monoclonal antibody Pab240, fast red chromogen, counterstained with methyl green, ×250).
