Vizualization by electrophoresis on a 2% agarose/ethidium bromide gel of serial 10-fold dilutions of final HHV-8 N-PCR1′ amplified products in Kaposi’s sarcoma (KS) sample from AIDS-1, and in lymph node (LN), spleen (S), bone marrow (BM), and myeloma (Myel) samples from POEMS-1. The molecular size (in base pairs, bp) of the expected amplified product for HHV-8 ORF26 (170 bp) and molecular-weight markers (100-bp DNA ladder; GIBCO-BRL, Gaithersburg, MD) are indicated on the left.
