A brief schematic of the assays for testing the effect of polyanions on HIV-1 infection in the presence of PAP248-286 or SE-F.

Abstract

<p>Polyanions at graded concentration was mixed with an indicated concentration of PAP248-286 or SE-F at an indicated interval with agitation as described in the “<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0059777#s2" target="_blank">Materials and Methods</a>”. After centrifugation, the supernatants were collected for testing the inhibitory activity of the unbounded polyanions on HIV-1 infection. The pellets containing the PAP248-286 (SEVI) - or SE-F-derived amyloid fibrils were re-suspended in 100 µl medium for testing the enhancing effect on HIV-1 infection.</p
