Example: "The two objects are physically bound to each other by a strong magnetic force."
Alternatives: "are physically connected to" or "are physically tied to".
Furthermore, we demonstrate that MSI2 protein is physically bound to FLT3 mRNA transcripts, suggesting post-transcriptional control of FLT3 expression.
In addition, to determine whether LIPA was physically bound to the silica particles, we also started the reaction by adding 15 μL of LIPA after preparing a mixture of the silica particles, HLMs, buffer, and NADPH.
Next, to determine whether the silica particles were physically bound to microsome proteins, we centrifuged a mixture of silica particles, LIPA, HLMs, and buffer at 1,000 × g or 5,000 × g for 20 min and then added NADPH (15 μL) to the supernatant (45 μL).
Hence, we investigated whether Jmjd3 was physically bound to the promoters of these genes by chromatin immunoprecipitation (ChIP).
It's surely this psychological double-bind we're tangled up in that makes us feel either a passionate sympathy for these men who are physically bound and about to suffer such barbarism, or indifference to their fate.
The conclusion of the study was that CAP is physically bound at many thousands of places in the genome.
Serum differs from plasma in that the bulk of the fibrinogen has been removed by conversion into a fibrin clot together with the platelets that have either been physically bound in the fibrin matrix or activated to form aggregates or both [ 45].
SEM and HR-TEM images proved the existence of visible coverage of dispersant on the surface of individual nanoparticles and showed that thin polyelectrolyte layers were physically bound onto the particles' surfaces.
To understand which one of the two putative responsive elements found in the " in-silico" analysis is physically bound by OTX2, driving the expression of TAp63, we performed a ChIP analysis using chromatin of transfected cells pulled down using OTX antibody.
