Abstract
- Microfluidic strategies combined with transduction and electronic integration have the promise of enabling miniaturized, combinatorial assays at higher speeds and lower costs, while at the same time mimicking the local chemical concentrations and force fields of the cellular in vivo environment. In this chapter we introduce a microfluidic structure with hydrodynamic cell traps and a culture volume in the nanoliter range (50 nL), to quantitatively evaluate the transient calcium response of the endogenous Muscarinic type 1 receptor (M1) in HEK 293 T cells. The microfluidic fabrication protocol is described as well as a methodology to monitor the cell response in real time, after stimulation with M1 agonists (e.g., carbachol) and antagonists (e.g., Pirenzepine).
