Quantitative Fluorescent PCR (QF-PCR) on microsatellites, a fast and quantitative method to assay chimeric DNA samples in honeybees (Apis melliferà)

摘要

The production of chimeras by nuclear transfer or cell transplantation requires functional tools for the detection of individuals that have successfully incorporated donor material. Quantitative Fluorescent PCR (QF-PCR) on microsatellites was employedon artificial chimeric honeybee DNA samples, to develop protocols for detection and quantification of donor genotypes after nuclear transfer and cell transplantations into honeybee embryos. Standard curves were produced for three microsatellite markersand demonstrate that there is a close to linear correlation between the amounts of donor genotypes estimated with QF-PCR and actual amounst of genotypes. The method was sensitive down to a 1% level and could detect and quantify small amounts of donor DNAin artificially mixed samples. QF-PCR offers fast and sensitive detection and quantification of genotypes and, thus, provides a useful tool for studies of chimeric honeybees and other species.
