Expression analysis of HERV-K mRNA splice products in primary GBM cells by semiquantitative RT-PCR. Three different primary cell cultures, derived from patients’ biopsies, were passaged 6 times. Total RNA was isolated from passage 2 and passage 6 and used for semiquantitative RT-PCR as described in Figure 2.
