We detected surface N on the two infected cells and non-infected neighboring cells24. N, like all N proteins, is very positively charged, and binding of endogenous N and cell-derived or recombinant N to cells needs heparan sulfate/heparin (very negatively billed proteoglycan), as revealed by the abrogation of binding by enzymatic https://magnetic-beads-rna-isolat14792.diowebhost.com/84755190/the-basic-principles-of-magnetic-beads-dna-extraction
