(4) Since the introduction of dideoxynucleoside reverse transcriptase inhibitors (NRTIs) in 1985 and after the approval of the first protease inhibitor in 1995, the availability of new fixed-dose combinations regimens of new antiretroviral drugs, evolved faster in the developed world.

Lamivudine (3TC), the negative enantiomer of 2'-deoxy-3'thiacytidine, is a dideoxynucleoside analogue used in combination with other agents in the treatment of human immunodeficiency virus type 1 (HIV-1) infection and as monotherapy in the treatment of hepatitis B virus (HBV) infection.
Assay-specific deoxynucleoside triphosphates (dATP, dGTP, dTTP; Amersham) and dideoxynucleoside triphosphates (ddA, ddC, ddG, ddT; BioLog Life Science Institute) were added at 0.12 mmol/L.
Therefore, in that study, a very short extension strategy using alternating deoxynucleoside triphosphates (dNTPs) and dideoxynucleoside triphosphates was adopted so that the products differed in mass by [M.sub.r] 300 to 400 to resolve the 50/50 heterozygote for direct quantification from mass spectra.
Primer extension reactions were carried out in a 20-micro]L volume containing 50 ng of input PCR product and 0.75 [micro]M primer, 25 [micro]M each of the dideoxynucleoside triphosphates (Amersham Pharmacia Biotech), and 0.5 U of ThermoSequenase DNA polymerase (Amersham Biosciences) in 1 x supplied reaction buffer.
Our strategy for detecting the splice variants expressed from the genes is based on the extension of gene-specific minisequencing primers with fluorescent dideoxynucleoside triphosphates (ddNTPs), each of which define a specific splice variant (see Table 52 in the online Data Supplement).
