rgp-46I/II, type-specific recombinant Env proteins; P19 and P24, Gag proteins; GD21, Env protein.
For PCR (tax) and PCR (LTR), of 208 positive samples, 50 were randomly tested for tax and LTR regions of the HTLV-1 genome by PCR amplification, which confirmed the WB results.
All HTLV WB-positive specimens were determined to be HTLV-1 positive by PCR amplification.
