作者用硫酸葡聚糖和肝素在携带I型人类嗜T淋巴细胞病毒(HTLV-I)MT-4细胞和人类白血病T细胞系Molt-4中作抑制病毒活性试验。用HIV感染细胞,待病毒吸附后,再加入不同浓度的硫酸葡聚糖和肝素。经培养后用台盼蓝排除法检测活细胞。用间接免疫荧光法检测病毒特异性抗原,用逆转录酶试验检测硫酸葡聚糖对逆转录酶活性的抑 The authors used dextran sulfate and heparin to inhibit viral activity in carrying human type I human T-lymphotrophic virus (HTLV-I) MT-4 cells and the human leukemia T cell line Molt-4. Infected with HIV cells, until the virus adsorption, then add different concentrations of dextran sulfate and heparin. After incubation with trypan blue exclusion assay of living cells. Indirect immunofluorescence assay was used to detect virus-specific antigen, and reverse transcriptase assay was used to detect the effect of dextran sulfate on reverse transcriptase activity
