NBC1 Antibody – Rabbit Polyclonal

Bicarbonate, along with CO2, is the major pH buffer of biological fluids. The inter-conversion of CO2 to HCO3- is mediated by family of carbonic anhydrases. Several organs specialize in the mobilization of HCO3-. The pancreatic ducts move CO2 and HCO3- from the blood into pancreatic secretions. The kidneys reabsorb massive amount of HCO3- daily (amount of NaHCO3 contained in 1 Ib of baking soda) through the glomerular flirtation of ~180 liters of plasma. To prevent a massive acidosis, the proximal tubules (PT) cells in the nephron subsequently reabsorb virtually all of HCO3-, as well as most of the filtered Na+, Cl-, and H2O. A great majority of HCO3- reabsorption occurs via trans-cellular coupling of the luminal Na-H+ exchanger 3 and Na+-H+ ATPase with the basolateral Na+ HCO3- cotransporters (NBC). Several related proteins constitute the emerging NBC family (NBC1-3) of membrane cotransporters that are found in a variety of epithelial and non-epithelial tissues, and may be tissue specific. Physiologically, NBC is electrogenic, Na+ and HCO3- dependent, Cl- independent, and inhibited by stilbenes (DIDS and SITS). The NBC family of proteins are 30-35% related to anion exchangers (AE2 and AE3; SLC4A1-SLC4A3) and display the same protein topology: (a) At least 10 TM domains with both the N and C-termini predicted to be intracellular, (b) presence of a large, glycosylated, extracellular loop between TM5 and TM6; and (c) the lysine residues are conserved at predicted DIDS-reactive sites.

Small volumes of anti-NBC1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS615018 is an antibody targeting NBC1. Also known as NBC1 (HCO3 Cotransporters 1, pNBC). Reactive in Rat. Host: Rabbit.
