Integrated RNA ISH and ICC staining on HPV markers. Integrated RNA ISH and ICC staining with customized conjugated CK8, 18, 19-AF488 antibody (ICC), HPV16 E6, E7-type 1 (RNA ISH), and EGFR-AF647 antibody (ICC). The HPV16 E6, E7-type 1 probe is the 1:1 mixture of HPV16 E6-type 1 and HPV16 E7-type 1. (A,B) presents the staining of blood cells spiked with SCC90 (A) or SCC47 (B) cells at a ratio of 4:1 in cell number. (C) shows the staining of the NME cells from head and neck cancer patients. Among these NME cells shown in (C), HPV+, EGFR+, CK+, or CK− cells are found. (D) is a specificity test with the staining of blood cells spiked with BT474 cells at a ratio of 4:1 in cell number. Both BT474 cells and blood cells are negative on HPV. The specificity of this test is hence proved.
