| 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. | | | NBC1 (human, rat, mouse 1035 aa, also called NBC-1A/1B, hkNBC, rkNBC, pNBC, hhNBC, SLC4A4) was initially cloned from human Kidney. NBC1 is 30-35% identical with AEs. It is strongly expressed in the kidney and pancreas. The rat kidney NBC1 (rkNBC1; 1035 aa) is 86% identical to hkNBC1. Pancreatic NBC (pNBC/hhNBC/SLC4A5, human 1079 aa) has a unique n-terminal 85 aa sequence replacing the 41-aa in kNBC. pNBC is also more widely expressed (pancreas, thyroid, heart, and brain). | | | Catalog # | N0536-05A | | Applications | Suitable for use in ELISA and Western Blot. Other applications not tested. | | Recommended Dilution | ELISA: 1:10K-1:100K using 50-100ng of control peptide/well. | | Western Blot: 1-10ug/ml using ECL. | | Optimal dilutions to be determined by the researcher. | | Storage and Stability | May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | | CAS Number | n/a | | Clone Type | Polyclonal | | Host | Rabbit | | Source | Human | | Concentration | 1mg/ml | | Form | Supplied as a liquid in 100mM Tris, pH 7.5, 0.2% BSA, 0.05% sodium azide, 40% glycerol. | | Purity | Purified by affinity chromatography. | | Immunogen | A 20-aa peptide sequence within the cytoplasmic, N-terminus of human NBC1 (1) was used to generate anti-NBC1. The peptide was coupled with KLH (carrier protein) | | Specificity | Human sequence is 100% conserved in mouse, rat, human and rabbit NBC1/PSLC4A4/kNBC and 75% in frog NBC1. This region is also shared 100% with pNBC/ PSLC4A5. Therefore, antibodies will recognize both the kidney and pancreatic/heart isoforms. No significant sequence homology of was found with NBC2 or NBC3. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
