Immunofluorescence analysis of Pannexin 2 was done on 90% confluent log phase Caco2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Pannexin 2 Rabbit Polyclonal Antibody (422900) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing membranous localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Gap junctions are channel-forming structures that allow direct metabolic and electrical communication between adjacent cells of almost all types in mammalian tissues. In the human body, they are absent only in adult skeletal muscle cells and some circulating blood cells. A gap junction is formed two hemichannels, one in each of the neighboring cells, composed of six subunits. In mice and humans, at least 20 connexin and 3 pannexin genes encode gap junction proteins. Connexins are only found in chordates, while pannexins are present in both chordate and invertebrate genomes. Pannexins, previously known as innexins, are predicted to have four transmembrane regions, two extracellular loops, one intracellular loop, and intracellular N- and C-termini. Both human and mouse genomes contain three pannexin-encoded genes. Pannexin 2 (Px2, PANX2) appears to be a brainspecific gene, and is abundantly expressed in the central nervous system, as is pannexin 1. In many neuronal cell populations, including hippocampus, olfactory bulb, cortex, and cerebellum, pannexin 1 and pannexin 2 are co-expressed; in other brain regions such as white matter, only pannexin 1-positive cells are found.
