Yоu аre using flоw cytоmetry to аnаlyze primary T cells from a person with lymphoma. You label the cells with fluorescent antibodies against several cell surface receptors: CycD3, CD79a, CD4, and CD8. You obtain the charts shown below. In the data analysis, you remember that each dot represents one cell. Briefly answer the following: 1) In the left chart (quadrants labeled B), where are the majority of cells found? What does this mean for which cellular proteins they express? 2) In the right chart (quadrants labeled E), do most cells express no marker, one of the markers, or both of the markers? (The answer can be a combination of these choices.) 3) What is one advantage and one disadvantage to studying these primary T cells? Image from: Tuan Nguyen T, Thi Vinh Do A, Thi Nguyen N, et al.
