Comparative analysis and physiological impact of different tissue biopsy methodologies used for the genotyping of laboratory mice.

Abstract excerpt

Genotyping of genetically modified mice and control of authenticity of the genetic background of congenic or coisogenic strains by polymerase chain reaction (PCR) is a routine procedure that can be performed with different tissue biopsies causing variable grades of trauma. In this study, some invasive and non-invasive sampling methods were compared, with the main focus on the impact on animal physiology. We...
