A flow instrument printout reveals a single scatter population of small size and low complexity.Ninety percent of the cells in that population have CD2 on their surface.What is the most probable lineage of the unknown population?
A)NK cells
B)T cells
C)B cells
D)Monocytes

Question

Quizplus · Accepted Answer

CD2 is commonly expressed on T cells, and the small size and low complexity of the scatter population suggests a population of lymphocytes. NK cells can also express CD2, but they typically have a larger size and higher complexity. B cells do not typically express CD2, and monocytes are not lymphocytes and would not be expected in a scatter plot of lymphocytes. Therefore, the most probable lineage of the unknown population is T cells.
