The best thing about Montana Molecular’s biosensors has been the ease of use. My lab has already been doing live cell imaging, mostly free Ca2+.  All we had to do is to infect the cells and use the same microscope set-up to gather data on PIP2, DAG and cAMP.

Robust Assays in Living Cells

» Easy assay steps – No cell lysis
» BacMam delivery to most cell types
» Fluorescence imaging or plate reader detection (Z’ > 0.8)
» Physiologically-relevant and cell friendly
» No forskolin or IBMX needed
» No enzymes or co-factors
» Multiplex GPCR Assays: Gs, Gq, Gi, Voltage
