HI, Recently we've been looking at data from lymphocytes, CD4 and CD8 cells undergoing apoptosis using Annexin V and have noticed that some lymphocytes and CD4 cells exhibit tailing in the bottom right quadrant of the dot plot - it almost looks very badly compensated. The plot attached is data from a sample given a dose of 1.0 Gy. The 0 Gy dose (and Controls) do not exhibit this pattern while samples that have been irradiated with more than 0.2 Gy do show this pattern. Does anyone have any thoughts on what this is from? (See attached file: flow plot.JPG) Thanks.
