This CD20/Side Scatter dot plot is gated on CD45+ events. Unlike the dot plots gated on Lymphocytes, it includes the named populations defined on the CD45/Side Scatter dot plot: lymphocytes (red), monocytes (green), granulocytes (blue), and blasts (pink). The blasts (normally colored pink but colored red in this case) do not express CD20. A small population of normal B lymphocytes is present in this sample.

ThisCD56/CD19dot plot isgatedonCD45+events. Unlike thedot plots gated on Lymphocytes, it includes the named populations defined on the CD45/Side Scatter dot plot: lymphocytes (red), monocytes (green), granulocytes (blue), and blasts (pink). The blasts (normally colored pink but colored red in this case) do not express either CD56 or CD19.

ThisCD34/CD10dot plot isgatedonCD45+events. Unlike thedot plots gated on Lymphocytes, it includes the named populations defined on the CD45/Side Scatter dot plot: lymphocytes (red), monocytes (green), granulocytes (blue), and blasts (pink). As noted elsewhere in this analysis, granulocytes (blue) express CD10. The blasts (normally colored pink but colored red in this case) express high density CD34.

This CD34/CD20 dot plot is gated on CD45+ events. Unlike the dot plots gated on Lymphocytes, it includes the named populations defined on the CD45/Side Scatter dot plot: lymphocytes (red), monocytes (green), granulocytes (blue), and blasts (pink). As noted elsewhere the blasts (normally colored pink but colored red in this case) express CD34.
