We detected surface area N on each contaminated cells and non-infected neighboring cells24. N, like all N proteins, is extremely positively billed, and binding of endogenous N and cell-derived or recombinant N to cells needs heparan sulfate/heparin (remarkably negatively billed proteoglycan), as proven via the abrogation of binding by enzymatic https://magneticbead60371.ageeksblog.com/28966857/not-known-facts-about-isolation-of-small-dna-fragment
