I'm trying to study apoptosis of 1. fresh mouse thymocytes induced by 2. TCR stimulation using 3. flow cytometry, either by 3a. Annexin V or by 3b. TUNEL. I know there are tremendous amount of literature related to this, but so far I have not come across with ones that contain all the "keywords" I listed above. Specifically, I found most of the study has been done using "immature" T cell lines or hybridomas instead of "fresh mouse thymocytes". I tried it a couple of times, but I cannot see any difference between cells stimulated with anti-CD3 and non stimulated control because a significant portion of cells are Annexin V (+) in the control. Any suggestions?
