We detected surface area N on both contaminated 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 (highly negatively charged proteoglycan), as demonstrated from the abrogation of binding by https://magneticbeadscellisolatio70368.qodsblog.com/29669246/the-2-minute-rule-for-viral-rna-isolation-kit
