Live Cell PIP2 Assays
Green or Red Fluorescent PIP2 Assays
- Bright fluorescent PIP2 sensor
- Real time kinetic assay
- Robust expression in a variety of cell types
PIP2 Assay Performance
- Genetically-encoded for low toxicity
- PIP2 sensor and controls are packaged in BSL-1 BacMam vector for efficient expression in a variety of cells
- Single channel readout can be combined with additional GPCR assays
- Real time kinetic readout
Multiplex Assays
Combine red and green sensors to measure multiple GPCR pathways simultaneously
Simple Protocol
-
- No cell lysis
- Single channel readout
- BSL-1 Vector
- Controlled expression levels
GPCR Biology
Increase your understanding of drug effects and GPCR biology with bright fluorescent assays for Gs, Gi, and Gq signaling in living cells.
