FIG. 4.
Inhibition of cell-associated FIV infection by peptide C8. PBMC, freshly harvested from long-term FIV-M2-infected cats and containing approximately 102 infectious units as determined in substrate MBM cells, were mixed with C8 (•) or C8scr (○). Test cultures were then processed as described for inhibition of cell-free virus except that the wells were not rinsed after contact and the medium added on day 4 contained appropriate concentrations of test peptides.
