From: Detection of human parvovirus B19 in papillary thyroid carcinoma
Laser-capture microdissection and nested PCR amplification for parvovirus B19 DNA in papillary thyroid carcinoma. (A–A1) Tumour cells of papillary thyroid carcinoma were microdissected. (B–B1) Glandular structures of tumour-adjacent tissue of PTC were microdissected. (C) Products of nested PCR from the microdissected tissues. Lane M: 100 bp DNA ladder. Lanes 1–5: specimens from neoplastic tissues; lanes 1′–5′: tumour-adjacent tissues; lane N: negative control; lane P: positive control. The amplicons were approximately 173 bp in size. Original magnification: × 400 (A–A1); × 200 (B–B1).
