Inhibition of HIV transcytosis across HEC-1 epithelial cells, forming a model of human epithelium. Cord blood specimens from EUN newborns were tested in transcytosis inhibition assays using the HIV-1 SF162 strain (two replicas). Results are expressed in percentages compared to results with 2F5 MAb (>85% inhibition; positive control) and a pool of HIV-negative cord blood samples (100% transcytosis; negative control [CTRL]).
