Cd8a-IRES-Luc-2A-EGFP

A V5-IRES-luci-2A-EGFP expression cassette was inserted before the stop codon TAA of mouse Cd8a gene to establish a multi-labeled knockin model with V5, luciferase and EGFP fluorescent protein.

Figure 1  In the absence of any stimulation, the in vivo imaging system detected that Cd8aV5-IRES-luci-2A-EGFP/+ mice showed significant fluorescence.
