Cell Signaling – Multimedia

Whilst conducting an evaluation of label free technology platforms we encountered a number of surprising, but reproducible, observations. For example, receptor over-expression impacts endogenous signaling responses; surface coatings affecting cell adherence can change the response profile; and it is important to choose the appropriate analysis metric for complex profiles. Awareness of the subtleties of cell signaling within model systems such as CHO and HEK recombinant over-expression sys

Successful RNAi experiments and large-scale siRNA screens require efficient delivery of highly functional and specific nucleic acids including siRNA oligonucleotides, shRNA vectors, or micro RNAs into an appropriate cell system. Cell types relevant for immunological research, such as primary T cells and several suspension cell lines, are poorly accessible using reagent-based transfection approaches.

The activation of GPCRs is known to lead to the dynamic translocation of multiple signaling molecules or molecular assemblies during its signaling cycle, and in many cases cytoskelatal reorganization. Such a movement and/or reorganization results in dynamic redistribution of cellular contents, equivalent to dynamic mass redistribution (DMR), which can be monitored online in living cells using Corning® Epic™ system – a label-free and non-invasive biosensor system.
