Figure 1. Reverse transcription-polymerase chain reaction (RT-PCR) analysis of MUPP1 in mouse tissue. RNA isolated from mouse testis and cortex as well as from the germ cell lines GC-1spg (GC1) and GC-2spd (GC2) was subjected to RT-PCR analysis using specific primers for MUPP1 (lanes 1) and ß-actin (lanes 2). The PCR-products resulted in bands of the predicted sizes (MUPP1: 250 bp; ß-actin: 425 bp). The 100-bp ladder DNA size marker is shown for each pair of PCR products.
