Figure 3.
NBS1 foci on DP T cells from RYIIRAG1 −/−, RAG2 −/−TCRβ transgenic, and wild-type mice. DP thymocytes were stained with anti-NBS1 (green) and counterstained with Topro-3 (red). (A) WT, (B) RAG2 −/−TCRβ, and (C) RYIIRAG1 −/−. 460–480 DP cells were examined for each mouse strain for the presence of foci.
