The goal of this study was to determine if flow cytometry could be used to identify transgene carrier mice [B6.Cg-Tg(Prdm1-EYFP)1Mnz/J] by their expression of the enhanced yellow fluorescent protein (eYFP) in peripheral blood lymphocytes. In these mice, eYFP expression is under the control of the Prdm1 gene promoter. Littermates were identified as being either wild type or transgene carriers using a polymerase chain reaction (PCR) analysis of tail tissue. Peripheral blood leukocytes were isolated from each of the mice, and both the percent and mean fluorescence intensity (MFI) were determined for eYFP expression by lymphocytes. We found that blood lymphocytes …
