PCR amplification with species specific primer pairs. PCR analysis of genomic DNA from rat, mouse and human cell lines and primary tissue using species specific primer pairs. PCRs assays used and source of input DNA (50 ng each) are shown. Amplified products generated at 32 cycles were detected by ethidium bromide staining of 1.5% agarose gels and UV transillumination. Blood refers to human peripheral white blood cells. RNase free water was used as negative control. Arrows indicate the DNA molecular weight marker of 500 bp (Hyperladder IV; Bioline)
