Effect ofι-carrageenan on virus adsorption.
A) HPV16, B) HPV18, C)HPV31, and D) HPV45 were incubated in the presence or absence of carrageenan (0 µg/ml and 100 µg/ml) and added to HaCaT cells at an MOI of 25. The virus was allowed to attach to HaCaT cells for 2 hours at 4°C. Analysis of the number of particles was done by SYBG q-PCR with attachment in the absence of carrageenan set to 100%.
