To determine whether the p16INK4a antibodies give similar staining patterns in human tissue, IHC analysis of the F-12 and JC8 antibodies was performed on serial tissue sections alongside the antibody E6H4 (Figure 4) which is commonly used for the identification of p16INK4a in cervical cancer tissue in IHC tests [12]. The gene discussed is CDKN2A; the disease is cervical cancer.
