Expression and Purification of a Mammalian P2X7 Receptor from Sf9 Insect Cells

[Abstract]  The P2X7 receptor is an extracellular ATP-gated ion channel found only in eukaryotes (Bartlett et al., 2014). Due to its unique properties among P2X receptors, such as formation of a large conductance pore, the P2X7 receptor has been implicated in devastating diseases like chronic pain (North and Jarvis, 2013). However, mechanisms underlying the P2X7 specific properties remain poorly understood, partly because purification of this eukaryotic membrane protein has been challenging. Here ...

Endpoint or Kinetic Measurement of Hydrogen Sulfide Production Capacity in Tissue Extracts

[Abstract]  Hydrogen sulfide (H2S) gas is produced in cells and tissues via various enzymatic processes. H2S is an important signaling molecule in numerous biological processes, and deficiencies in endogenous H2S production are linked to cardiovascular and other health complications. Quantitation of steady-state H2S levels is challenging due to volatility of the gas and the need for specialized equipment. However, the capacity of an organ or tissue extract to ...

Bacterial Survival in Dictyostelium

[Abstract]  We performed an assay to test the ability of different E. coli strains to survive inside amoebal cells after ingestion. In the assay we incubated bacteria together with cells of Dictyostelium discoideum for six hours. After co-incubation most of the uningested bacteria were removed by centrifugation and the remaining uningested bacteria were killed by gentamicin. Gentamicin is used because it does not penetrate into eukaryotic cells allowing the ingested bacteria to survive ...
