Abstract

The present invention relates to the field of biomedical detection, particularly to a fluorescent cell counting detection kit for detecting tumor markers, wherein the fluorescent cell counting detection kit comprises a CD14 antibody and a CD16 antibody for labeling cell surface antigens, and an antibody for labeling intracytoplasm antigen, the intracytoplasm antigen is TKTL1 and / or DNASE1L1, and the kit further comprises a microscope glass slide.

Description

technical field [0001] The invention relates to the field of biomedical detection, in particular to a fluorescent cell counting detection kit for detecting tumor markers. Background technique [0002] Monocyte-macrophages include promonocytes in bone marrow, monocytes in peripheral blood, and macrophages in tissues. Human peripheral blood cells are mainly divided into anucleated cells (mainly red blood cells) and nucleated cells (white blood cells, etc.). Monocytes account for about 5% of the total number of nuclear cells and are differentiated from myeloid hematopoietic progenitor cells. They are important components of antigen-presenting cells (APC cells) in the immune system. [0003] In the peripheral blood circulation of the human body, white blood cells are distributed in two places, namely, the circulation pool and the storage pool. Circulation, but the leukocytes in the storage pool maintain a dynamic balance with the leukocytes in the circulating pool. The matura...
