| Description: | 1. HEK293 cells which can stably express CCR5 were inoculated in a 96-well plate and incubated overnight.2. The medium in each well into which cells were innoculated was removed and 40 μl/well of freshly prepared dye was added. The plate was placed in a 37° C. incubator and incubated for 40 minutes at constant temperature.3. The medicament to be determined was diluted with calcium buffer to eight concentration gradients, which is 1×10−4 M, 1×10−5 M, 1×10−6 M, 1×10−7 M, 1×10−8 M, 1×10−9 M, 1×10−10 M, and 1×10−11 M, respectively, and homogeneously mixed.4. The dye was removed. Freshly prepared calcium buffer was used to wash for one time, 50 μl of calcium buffer was added.5. FlexStation II was used for detection. 25 μl of calcium buffer containing the medicament to be determined was added automatically from the 15th second. The fluorescence value at 525 nm was read ultimately. |
