In order to establish whether the interactions between Dsg3 and E-cadherin that we had detected by confocal microscopy and co-immunoprecipitations were indeed real we used the acceptor photobleaching FRET technique [38].
Furthermore, to establish whether the observed interaction between ORF57 and PYM was direct, GST-pull-down experiments were performed using purified baculovirus-expressed recombinant ORF57-6xHis protein and a negative control baculovirus-expressed protein, HIV-Nef-6xHis (Harris and Coates, 1993).
To establish whether this interaction occurred during monocyte activation, we immunoprecipitated FOXO3 from stimulated monocytes and found that the DNA to which it was bound included the predicted binding site from the TGFβ1 promoter, confirming that a direct protein-DNA interaction occurs.
Consequently, wider sampling is still needed to help establish whether the Hox-TALE interactions characterised by Hudry et al. really did originate with the cnidarian-bilaterian ancestor or if, in fact, they were established even earlier.
To establish whether the NTD directly mediates interaction with TARPs, we first used immunoprecipitation (IP) to test if the NTD contributes to stabilizing the AMPAR-TARP complex.
Future studies in larger population-based samples will be necessary to establish whether the DNA methylation signals identified here, also interact with genetic variants, or are subject to gene-environment interactions.
[20] To establish whether the introduction of a probe interferes with the Pc Cyt f interaction, chemical shift analyses were carried out for all variants.
We evaluated the cytokine secretion profile of PBMC and B cell/CD4 T cell cultures to establish whether the cytokine profile induced by B cell-CD4 T cell interaction is similar to that induced when all PBMCs participate.
