Cells were then permeabilized using 0.25% Triton X-100 for 10 min. PBS supplemented with 10% goat serum was used to block non-specific binding and cells were then incubated with the primary antibody overnight at 4°C.
The DNA-based qPhage methodology allows full quantification of phage content, binding, and cell internalization, with a superior performance compared to conventional TU-counting.
By presenting biomolecular ligands on the surface in high density, ligand-decorated dendrimers are capable of binding to membrane receptors and cells with specificity and avidity.
We identified variations DNA repair and viral binding and cell entry genes associated with CIN3/cancer.
However, P. gingivalis cannot synthesize this iron porphyrin and thus acquisition from exogenous sources, coupled with its binding and cell surface storage, is essential for the growth and survival of this bacterium.
The model is based on mass-action kinetics describing binding and cell surface trafficking interactions for VEGF with VEGFR1, VEGFR2, NP-1, and ECM sites and builds on previous work from Popel and co-workers[ 15- 20].
Moreover, cell membrane binding and dendrimers cell uptake together with fluorophore-conjugated oligonucleotides was evaluated using TIRF microscopy showing dendrimers different behavior with the plasma membrane.
By combining an improved oligosaccharide synthetic route with protein-binding and cell-growth assays, Caltech researchers can investigate the biological roles of specific glycosaminoglycan sulfation patterns.
For binding and internalization, cells were preincubated with Rh-EGF at 4°C to allow for binding, followed by removal of unbound Rh-EGF incubated for the indicated times and concentrations with Rh-labeled EGF at 37°C, and then washed with either PBS or an acidified buffer as described previously [ 30], followed by ALDH1 staining.
To address whether MYCN represses LFG directly, a chromatin immunoprecipitation (ChIP) data set was examined for MYCN binding in Tet21N cells with and without doxycycline treatment.
