Abstract

The invention discloses liquid-base cell preservation liquid as well as a preparation method and application thereof, relating to the technical field of biology. The liquid-base cell preservation liquid contains the following components in parts by weight: 12-18 parts of a fixing agent, 2-8 parts of an anti-coagulation agent, 2-10 parts of a buffer agent, 0.5-0.8 part of an ion strength maintaining agent, 2-8 parts of an antimicrobial reagent, 0.05-0.2 part of a mucus dissolving agent and 0.1-0.4 part of a cleanser. The liquid-base cell preservation liquid has the advantages that the cell stability is high, cells are well fixed, the cost is low, the preserved cell forms are relatively complete, and the like. Besides, the invention further provides the preparation method of the liquid-basecell preservation liquid and application of the liquid-base cell preservation liquid in human body cast-off cells.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a liquid-based cell preservation solution and its preparation method and application. Background technique [0002] The incidence of cervical cancer ranks first in female reproductive tract malignancies. There are nearly 500,000 new cases of cervical cancer every year in the world, 83% of which occur in developing countries, and 131,500 new cases occur in my country, accounting for 28.8%. About 290,000 people die of cervical cancer every year in the world, and about 30,000 people in my country. Therefore, the prevention and treatment of cervical cancer has become a global public health problem. [0003] Thin-Cytologic Test (TCT) uses a liquid-based thin-layer cytology detection system to detect cervical cells and perform cytological classification and diagnosis. It is currently an advanced cervical cancer cell test in the world. Compared with the traditional cervical smear and Pap...
