Methods for amplifying genetic material and uses thereof

摘要

The present invention concerns a method of making a transgenic non-human animal cell which is totipotent or totipotent for nuclear transfer and which cell comprises amplified copies of a nucleic acid sequence of interest. The method comprising subjecting a cell from a host cell population to a gene amplification protocol to produce a cell which retains its totipotency or totipotency for nuclear transfer and which comprises amplified copies of the nucleic acid sequence of interest. Because the resulting cells retain totipotency, or totipotency for nuclear transfer, they may be used to generate a transgenic non-human animal which expresses amplified copies of a gene of interest. Consequently, high levels of a product of interest may be obtained from the animal.
