In Vitro	2-Naphthylamine-6,8-disulfonic acid potassium (compound 20) can inhibit human immunodeficiency virus HIV-1 and HIV-2 by 11% and 13.6% at a concentration of 1369 μM, respectively[1]. 2-Naphthylamine-6,8-disulfonic acid potassium (ANDS) can directly analyze polyglycolic pyrophosphate-linked oligosaccharides in cell cultures and tissues[3]. Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).Labeling oligosaccharides[3]: 1. Prepared 0.15 M ANDS with 15% (v/v) acetic acid. 2. Prepare 1M solution of sodium cyanoborohydride in dimethyl sulfoxide (DMSO). 3. Add 5 μL ANDS reagent (1 μL if sample is below 200 pmol) to the sample. 4. Add 5 μL sodium cyanoborohydride solution (1 μL if sample is below 200 pmol) to the sample. 5. After mixing, the reaction was briefly centrifuged and allowed to dry for 18 hours at 37 °C.
