We detected surface area N on both infected cells and non-contaminated neighboring cells24. N, like all N proteins, is highly positively charged, and binding of endogenous N and cell-derived or recombinant N to cells calls for heparan sulfate/heparin (remarkably negatively charged proteoglycan), as revealed through the abrogation of binding by https://rnabeads69246.wikibriefing.com/2826079/detailed_notes_on_rna_isolation_from_bacteria
