The level of H19 transcripts in heterotopic subcutaneous tumors after injection of the ES-2 cells determined by RT-PCR. "M"100-bp molecular weight marker. Lines 1–4 – heterotopic subcutaneous tumors from different mice and Line 5 – negative control. The sizes of the PCR products are 300 bp and 213 bp for human H19 and Histone internal control respectively.
