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 requires heparan sulfate/heparin (highly negatively charged proteoglycan), as proven via the abrogation of binding by enzymatic https://finnssrpn.wiki-promo.com/134545/new_step_by_step_map_for_ultra_trace_amount_of_cells_rna_extraction
