Objective: To develop an immunocytochemical technique for p16INK4a protein detection in scraped cervical cells for cancer screening.
Study Design: We took duplicate cervical scrapes from each participant, the first for a Pap smear and the second for p16INK4a protein detection. From a 50-microL cell suspension prepared from the scrape rinsing, a 10-microL aliquot was dropped in a 5-mm-diameter circle on a glass slide, air dried and fixed in 0.
