”Live-cell assays for cell stress responses reveal new patterns of cell signaling”

Identify cell stress from misfolded proteins in the ER and cytoplasm

n.s. = not significant,    * = pval < 0.05,    ** = pval < 0.01

Detection of cell stress using the ratiometric cell stress biosensor (#U0901G).

Left: Stress detection in cells expressing WT and mutant rhodopsin, which folds in the ER.

Right: Stress detection of cells expressing WT and mutant versions of α-synuclein, which folds in the cytoplasm.

Compare cell signaling responses in cells expressing WT or mutant proteins

HEK293T cells expressing the R-GECO Ca2+ biosensor (#U0600R) and WT or mutant P23H rhodopsin were stimulated with carbachol to produce a Gq-dependent Ca2+ signaling response. Mutant rhodopsin expression alters the Ca2+ signaling response

Use optogenetic tools to examine cell signaling in neurodegenerative models

Diagram of an optical-based assay to identify distinct profiles of phospho-diesterase (PDE) activity. The blue-light activated adenylyl cyclase bPAC (#V0100N) is combined with R-cADDis (#U0200R), a red fluorescent biosensor for cAMP, for cAMP production and detection respec-tively.
