Gene Affected TRPA1
Origin Trpa1-deleted Wistar (Crl:WI) strain was generated by using Zinc Finger Nuclease at Kirin Company, Limited in 2013. Exon 22-24, which form ion channel pore required for the activation in Trpa1 gene, was deleted.
Strain characteristics Noticeable phenotype is not observed under normal breeding. Intracellular calcium elevation treated by TRPA1-activating agent is not occurred under the calcium imaging using dorsal root ganglion neurons.
Breeding Conditions Good breeding.
Genotyping Determine by genomic PCR. Primer: Mt-F; CCTGATTTGCTCTGGCACA, Int24CellF; TGGGACTGTGTGGTGCT, Int24IgdelR; CCACAGTTCACCACCTTTCA PCR enzyme:KOD FX (Toyobo) Component Volume: template 1.0 μl Mt-F (10 μM) 0.75 μl Int24 lgdel R (10 μM) 0.75 μl Int24 Cel1 F (10 μM) 0.75 μl 2 x FX buffer 12.5 μl 2.0 mM dNTPs each 5.0 μl KOD FX 0.5 μl ddw 3.75 μl Total 25.0 μl Cycling condition (35 cycles): Predenature : 94.0 ℃ 2 min.
