Detection of expression level of protein P16 in lung neoplasms biopsy samples by flow cytometry / 中华检验医学杂志

ABSTRACT

Objective To improve the sensitivity of detection of protein P16 by FCM.Methods Protein P16 of blood cells and tumor cells in biopsy samples were labeled simultaneously with anti-CD45 and anti-P16 fluorescent antibody.The rates of CD45+P16+ cells and CD45-P16+ cells were calculated by FCM.Results The low expression rates of protein P16 in normal blood cells and in tumor cells in biopsy samples were 15.39%(6/39) and 69.23%(27/39),respectively, which had a significant differences (P
