We present protocols for the application of our targeted genetically-encoded calcium indicator (GECI) CatchER+ for monitoring rapid calcium transients in the endoplasmic/sarcoplasmic reticulum (ER/SR) of HEK293 and skeletal muscle C2C12 cells using real-time fluorescence microscopy. A protocol for the in situ Kd measurement and calibration is also discussed.
Neuronal excitability can be modulated through a dynamic process of endo- and exocytosis of excitatory ionotropic glutamate receptors. Described here is an accessible, high-content assay for quantifying surface and internal receptor population pools.
We describe here a method for growth of Neisseria gonorrhoeae in metal-restricted liquid medium to facilitate the expression of genes for metal uptake. We also outline downstream experiments to characterize the phenotype of gonococci grown in these conditions. These methods may be adapted to be suitable for characterization of metal-responsive genes in other bacteria.
Presented here is a method for investigation of the roles of the Na+/K+ pump and persistent Na+ current in leech heart interneurons using dynamic clamp.
This protocol describes an animal model for studying how early-life adversity, provoked by an impoverished environment and unpredictable maternal care during the early postnatal period, affects brain development and the future risk of mental disorders.
