Genetic ablation information


Genetic ablation occurs when a gene is deemed “null” through the homologous genetic recombination of a gene. It is utilized in the selective suppression of a specific cell line or cell type. This genetic engineering technique does not limit growth suppression to just the activity of an individual gene.[1] Specific cell ablation enables the examination of the in vivo activity of cells. An example of this method in action can be seen through the production of a knockout mouse. This is accomplished through the administration of one or more transgenes into a fertilized mouse oocyte’s pronucleus. Afterwards, it is reimplanted into a host mother, who then births a transgenic mouse. The transgenic mouse carries one copy of the transgene3 out of several hundred. From these mice, a homozygous colony can be created through breeding.[2]
