Figure 4. The intensity of the fluorescent eye markers allows differentiation of heterozygous from homozygous transgenic mice.

Figure 4

(A) Heterozygous and homozygous adult mice carrying mCFP or tdTomato markers can be easily identified under a handheld flashlight. (B) Homozygosity in adult mice can also be determined more quantitatively using whole animal in vivo fluorescence imaging. (C) Neonatal mice carrying EGFP or tdTomato markers can also be easily identified as heterozygous or homozygous under a handheld flashlight. (* marks heterozygous animals, # marks homozygous animals)
