Abstract

The invention belongs to the technical field of clinical medical pathology and in particular relates to a p16INK4a immunolabeling color-developing kit for cervical liquid-based cells. The kit comprises a p16INK4a antigen preservation solution, a first antibody, a second antibody, a DAB (Diaminobenzidine) color-developing solution, an endogenous peroxidase blocking agent, confining liquid, a buffering solution, a positive reference substance and a negative reference substance. The kit provided by the invention has strong specificity; an antigen and antibody specific combination type dyeing method is utilized and the defect that the specificity of non-specific Papanicolaou staining and naked-eye appearance judgment of current liquid-based cytology are overcome.

Description

technical field [0001] The invention belongs to the technical field of clinical medical pathology, and in particular relates to a p16 for cervical liquid-based cells INK4a Immunolabeling Chromogenic Kit. Background technique [0002] Cervical cancer is one of the most common malignant tumors of the female reproductive system in gynecology. Its incidence is second only to breast cancer and ranks second among female malignant tumors. It seriously threatens women's health and quality of life. China is a country with a high incidence of cervical cancer, accounting for about 1 / 3 of the world's incidence and mortality. Cervical cancer is currently the only cancer whose etiology is clear and can be completely cured through effective early diagnosis and treatment. [0003] The current early diagnosis of cervical cancer and precancerous lesions is divided into "three steps". The first step is vaginal exfoliation cytology examination to screen out suspicious cases. The second step...
