The cluster of differentiation (also known as cluster of designation or classification determinant and often abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules providing targets for immunophenotyping of cells. [1]

The cluster of differentiation (CD) is a protocol used for the identification and investigation of cell surface molecules present on leukocytes. CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell.

CD分子，又称分化簇（Cluster of Differentiation）或分化群，也叫白细胞分化抗原，是不同谱系的白细胞在正常分化成熟的不同阶段及活化过程中，出现或消失的细胞表面标记。

2021年2月21日 · 分化簇（cluster of differentiation, CD）专指白细胞膜上的抗原或抗原识别的抗体，又称为白细胞分化抗原。 多是细胞膜上的穿膜蛋白或糖蛋白 目前“CD”不仅代表白细胞表面抗原，还有红细胞、血小板和髓系细胞表面…

CD(Cluster of Differentiation)：分化簇或分化群，也叫白细胞分化抗原， 指的是不同谱系的白细胞在正常分化成熟的不同阶段及活化过程中，出现或消失的细胞表面标记。

CD分子（cluster of differentiation）应用以 单克隆抗体 （McAb）鉴定为主的聚类分析方法，将来自不同实验室的单克隆抗体所识别的同一分化抗原、其编码基因及其分子表达的细胞种类均鉴定明确者，统称CD。所鉴定的同一LDA 归为同一分化群（CD），即以CD代替以往的 ...

2023年7月7日 · CD markers, also known as CD antigens, are specific types of molecules found on the surface of cells that help differentiate one cell type from another. In fact, the initials "CD" stands for "cluster of differentiation," the nomenclature of which was first established in 1982.

分化群 [1] [2] （cluster of differentiation，CD）又称分化簇 [3] 、分化抗原 [4] 、CD抗原 [5] ，是一用於细胞表面分子的鉴定和调查的协议（protocol）或公约，该议定提供细胞 免疫表型 （ 英语 ： Immunophenotyping ） 分类的靶点 [6] 。

2018年7月30日 · The popular CD markers are CD138, which is expressed on multiple myeloma cells; CD33 expressed on cells of myeloid lineage; and CD52, which is expressed at high density by lymphocytes, monocytes, eosinophils, thymocytes, and macrophages.

CD markers, short for cluster of differentiation, are a system used to classify and identify specific molecules found on the surface of leukocytes, also known as white blood cells. Each CD marker is assigned a unique number, such as CD4 or CD8, allowing researchers and healthcare professionals to easily refer to them and understand their functions.
