Sodium Channel
Na channels; Na+ channels
Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. They are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (Voltage-gated, voltage-sensitive, or voltage-dependent sodium channel also called VGSCs or Nav channel) or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels). In excitable cells such as neurons, myocytes, and certain types of glia, sodium channels are responsible for the rising phase of action potentials. Voltage-gated Na+ channels can exist in any of three distinct states: deactivated (closed), activated (open), or inactivated (closed). Ligand-gated sodium channels are activated by binding of a ligand instead of a change in membrane potential.

DAPI
0 ImagesSynonyms: 4',6-Diamidino-2-phenylindoleDAPI (4',6-Diamidino-2-phenylindole) is a DAPI dye. DAPI is a fluorescent dye that binds strongly to DNA. It binds to the AT base pair of the double-stranded DNA minor groove, and one DAPI molecule can occupy three base pair positions. The fluorescence intensity of DAPI molecules bound to double-stranded DNA is increased by about 20 times, and it is commonly observed with fluorescence microscopy, and the amount of DNA can be determined based on the intensity of fluorescence. DAPI cannot penetrate intact cell membranes and is commonly used for staining damaged and fixed cells. DAPI (Compound 3) is an acid-sensing ion channel 3 (ASIC3) inhibitor. DAPI binds to ASIC3 and blocks the channel function. DAPI can be used in the study of chronic pain treatment (Ex/Em = 356/451 nm).
