From: Iota-Carrageenan is a potent inhibitor of rhinovirus infection
Effect of Iota-carageenan on HRV2 infected human nasal epithelial cells. A. Preincubation of virus with polymer. HNep cells were grown in 24-well plates were infected with HRV2 (0,1 TCID50/cell) in the presence of Iota-Carrageenan at the concentration indicated at the x-axis. 30 minutes after infection the inoculum was removed and medium containing Iota-Carrageenan with the concentration indicated was added. B. Treatment with polymer after infection. HNep cells were grown in 24-well plates were infected with HRV2 (0,1 TCID50/cell). 30 minutes after infection the inoculum was removed and medium containing Iota-Carrageenan with the concentration indicated at the x-axis was added. Viral titers in the supernatants of infected cells were determined after 48 h by TCID50 assay on HeLa cells (y-axis). Bars represent means of four parallel experiments, standard deviation is indicated.
