Truncated MTA-1: A Pitfall in ELISA-Based Immunoassay of HTLV-1 Infection

Figure 3

Amplification of HTLV-1 MTA1-coding region. A 455 bp fragment was amplified from the MTA-1 region of HTLV-1 genome. PCR products were electrophoresed in a 1.5% agarose gel, stained in ethidium bromide, and photographed. Lane 1, 100 bp ladder; lane 2, negative control; lane 3, PCR product from an ELISA positive patient; Lane 4, PCR product from an ELISA negative patient.
