Indeed, the integral binding avidity plays a predominant role in the targeting efficacy; the higher integral binding avidity increases the targeting efficacy.
To understand this further, we studied the effect of modulating glycan binding avidity on the systemic fate of AAV9 in mice.
For example, the HA mutation, K165E, increases receptor binding avidity whereas the mutations, K163T or S167F, do not apparently alter receptor binding avidity [13].
There are no simple correlations between HA receptor binding avidity and the emergence of compensatory NA mutations.
However, A12 has an extremely low binding avidity for the MHC, making that approach unlikely to be successful.
However, the low binding avidity of A12 for the major histocompatibility complex (MHC) made this strategy untenable.
For a given TF library, let N denote the sum of two subsets of BEs: (3) where N1 is the number of observed 'noise-rich' TF- DNA binding loci, having relatively low/moderate potential of TF binding avidity and N2 is the number of observed 'specific- rich' TF-DNA binding DNA loci, having a relatively high potential of TF binding avidity.
To improve integrin αvβ3-targeted imaging, the binding avidity for integrin αvβ3 has been maximized through the use of dimeric or multimeric cyclic RGD peptides [48, 50 52].
Naturally, TF-DNA binding avidity could be quantified by the number of TF molecules binding a given specific locus including specific binding element(s) and its flanking regions.
