The expression of introduced 2B4TCR α gene in
thymus. Thymocytes from KI mice were stained with
phycoerythrin-anti-CD4 antibody, and fluorescein
isothiocyanate-anti-CD8 antibody, and biotin-A2B4 antibody or
biotin-anti-CD3 antibody as described in Materials and
Methods. (A) CD4 and CD8 expression pattern of total
thymocytes and A2B4 positive thymocytes. (B) Four different
subpopulations (CD4+CD8−,
CD4+CD8+, CD4−CD8−,
and CD4−CD8+) of thymocytes of KI mouse were
gated and analyzed for the expression of KI TCR gene. (C)
The comparison of CD3 and KI TCR α chain expression in
CD4−CD8− DN thymocyte population.
