Figure 2: Immunohistochemical staining of endogenous human PIDD in different human tissues (paraffin sections) using MAb to PIDD (Anto-1) (Prod. No. ALX-804-837). Method: Different human normal (A: Bronchus; B: Kidney; C: Lung) or cancer (D: Breast; E: Ovarian; F: Colo-rectal) tissues were stained with MAb to PIDD (Anto-1) by standard immunohistochemistry.
