Finding immature cells using CD45-CD34 dot-plots
The following Flow Cytometry data represents blood analysis of a healthy volunteer (upper left) and three cases of acute leukemia.
Please answer the following questions:
1. True or False: The arrows points at the blast populations, which is very conspicuous in case AL 1 (upper right) and AL 3 (lower right).
2. True or False: In case AL 2 (lower left), the difference between the normal picture is more subtle and the blasts may be missed because in this case the blasts are CD34 negative.
3. True or False: In case AL 1, the cells are mostly CD45 negative.
4. True or False: In case AL 1, the cells are mostly CD34 negative.
5. True or False: In case AL 3, the cells are most opposite of the control.
6. True or False: In case AL 1, the cells are mostly CD45 and CD34 positive.
7. True or False: In case AL 3, the cells are mostly CD34 positive.
8. True or False: In case AL 3, the cells are mostly CD45 negative.
9. True or False: In case AL 2, the sample is most representative of the control.
10. True or False: In case of the control, most cells have high CD45 expression.
