WebElectrophysiology Xenopus laevis oocytes were injected with complementary RNAs (cRNAs) encoding OzTrac-MSL10-34 that were transcribed from linearized pOO2-GW-OzTrac-MSL10-34 plasmid. Each oocyte was injected with approximately 50 ng of cRNA. WebPico is ideally suited for whole cell (Vclamp and Iclamp) and single-channel (patch, planar lipid bilayer, and synthetic nanopore) recording, as well as cellular electrochemistry. Pico measures just 5.6″ x 1.8″ x 0.7″ 14.2cm x 4.5cm x 1.7cm, weighs 3 ounces (85 grams) and consumes less than 1 watt of power. grantley vinyl fence
