Question

Quizplus · Accepted Answer

CD2 is a surface marker found on T cells, making it highly likely that the scatter population is composed of T cells. The other options are less likely to express CD2, with neutrophils having low or no expression, B cells expressing it at lower levels than T cells, and monocytes having variable expression levels.
