Gene targeting strategy for B-hGDF15 mice.
The exons 1-2 of mouse Gdf15 gene that encode the full-length protein were replaced by human GDF15 exons 1-2 in B-hGDF15 mice.
Protein expression analysis
Species-specific GDF15 expression analysis in homozygous B-hGDF15 mice. Serum was collected from wild-type (+/+) and B-hGDF15 (H/H) mice and analyzed using a species-specific GDF15 ELISA kit. Mouse GDF15 expression was detectable in wild-type mice, while human GDF15 expression was exclusively detectable in B-hGDF15 (H/H) mice compared to wild-type.
