From: Is the presence of HCMV components in CNS tumors a glioma-specific phenomenon?
a Nested PCR analysis of viral DNA from clinical samples. Nested PCR demonstrates the presence of HCMV UL55 DNA sequences (146 bp) in tumor tissues of meningioma and metastatic carcinoma samples, but not in pituitary adenoma and cavernous hemangioma samples. Clinical samples: lanes 1,2, pituitary adenoma; lanes 3,4, cavernous hemangioma; lanes 5,6, metastatic carcinoma; lanes 7,8, meningioma. Positive samples in lanes 5–8 are the same samples positive for antigen reactivity. b Sequencing of the 146 bp PCR product
