- The exons 2-4 of mouse Lta gene that encode the full-length protein and 3’UTR were replaced by human LTA exons 2-4 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. The exons 1-4 of mouse Tnf gene including 5'UTR, 3'UTR and coding region were replaced by human TNF exons 1-4 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. The exons 1-3 of mouse Ltb gene that encode the full-length protein and 3’UTR were replaced by human LTB exons 1-4 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. The exons 2-6 of mouse Tnfr2 gene that encode the extracellular domain were replaced by human TNFR2 exons 2~6 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. The exons 2-6 of mouse Tnfr1 gene that encode the extracellular domain were replaced by human TNFR1 exons 2-6 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. The exons 1-7 of mouse Ltbr gene that encode the extracellular domain were replaced by human LTBR exons 1-7 in B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice.
- LTA protein was detectable in wild-type C57BL/6 mice and homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice, as the human TNF beta ELISA Kit can cross-recognize both human and mouse LTA. Mouse TNFA protein was only detectable in wild-type C57BL/6 mice, and human TNFA protein was only detectable in homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. LTB protein was detectable in wild type mice and homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice, as the antibody can cross-recognize both human and mouse LTB. Mouse TNFR2 protein was only detectable in wild-type mice. Human TNFR2 protein was only detectable in homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. Mouse TNFR1 was detectable on neutrophils of wild-type mice. Human TNFR1 was detectable on neutrophils of homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice. Mouse LTBR protein was detectable in wild-type mice. Human LTBR protein was detectable in homozygous B-hLTA/hTNFA/hLTB/hTNFR2/hTNFR1/hLTBR mice.
