Name | RuBi-Glutamate |
Description | RuBi - caged glutamate compound. Water soluble. |
Biological description | Ruthenium-bipyridine-trimethylphosphine (RuBi) - caged glutamate. Water soluble.
|
Alternative names | RuBi-Glu, RuBIglutamate |
Customer comments | Hello Bio produce very high quality Rubi-Glutamate, which is capable of evoking single spine synaptic currents following 2-photon activation. The spatial and temporal dynamics of the uncaging are suitable for fast photolysis, mimicking accurately endogenous glutamate release. Verified customer, The University of Edinburgh |

Biological Data
Application notes | Uncaging of Rubi-Glutamate using a 0.5 µm spot of 780 nm light for 2 ms (blue line), 1 µm adjacent to dendritic spines (average of 8 spine shown) in a CA1 pyramidal cell from a 28 day old rat. Traces were acquired using a cesium gluconate based intracellular solution in voltage-clamp configuration, in the presence of bath applied 300 µM Rubi-Glutamate and 50 µM picrotoxin (also Hello Bio), producing small AMPA EPSCs at -70 mV (top) and large NMDA EPSCs at +40 mV (bottom). |
