Effects of dynasore and NH ₄ Cl on GCRV entry. GCRV-JX01 virions at an MOI of 20 were adsorbed to CIK cells that had been pretreated with (a) DMSO(condition equal to the volume of dynasore used for the 50 μM), (b) 50 μM dynasore in DMSO or (c) 20 mM ammonium chloride (NH₄Cl) in water. After 1 h of viral adsorption at 0 °C, warm medium with inhibitors described above was quickly added. At 30 min post-infection (mpi), non-internalized viruses were removed and washed three times with PBS. Then cells were fixed with 4 % paraformaldehyde and permeabilized with 0.1 % Triton X-100 for 10 min at room temperature. The samples were labeled with an anti-GCRV VP5 polyantibody (green) and DAPI (Blue). Scale bars represent 20 μM
