Humanized Gene Knock-in Strategy


Figure 1. Targeting strategy for Trem2 gene CKO mouse model by ES cell targeting method.

Genotyping Strategy


Figure 2. Genotyping strategy for heterozygous F1 mice. Genotyping PCR was done using primer sets for the 5’ arm (regions 1 and 2) and 3’ arm (regions 3 and 4). The 5’ arm PCR yielded a 6.4 kb amplified fragment in the positive F1 mice and a 10.9 kb fragment would be amplified. The 3’ arm PCR yielded a 7.1 kb fragment in F1 positive mice and a 11.1 kb fragment in negative F1 mice.
