Breeding and genotype identification of NLRP3 gene knock-out mice / 第二军医大学学报

Objective: To breed and identify NLRP3 gene knock-out mice. Methods: The NLRP3 gene knock-out heterozygote mice were bred alone and copulated. The offsprings were to have three genotypes: wild genotype, heterozygote genotype and homozygote genotype. Genomic DNA was obtained from each pups and were subjected to PCR and T7 endonuclease 1 to identify the genotype. The homozygote mice were mated with the opposite sex heterozygote mice to obtain more homozygote pups. Results: Breeding and reproducing were both successful, and we obtained heterozygote genotype and homozygote genotype mice with NLRP3 gene knock-out. Conclusion: Correct methods of breeding, reproducing and identifying can effectively obtain NLRP3 gene knock-out mice from heterozygote mice.
