A 19-aa peptide sequence within the cytoplasmic, C-terminus of human NBC3. (KLH).
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). NBC3 (SLC4A), mouse (1089 aa, human 1044 aa) has 3 three transcripts, which are expressed in a tissue specific manner (9 kb in brain, placenta, lung, liver, muscle, kidney, pancreas, stomach, thyroid, and adrenal etc). NBC3 has two variants. NBC3 is 56% identical with NBC1 and 76% with NBC2. Applications: Suitable for use in ELISA. Western Blot, though not tested, may potentially be used as an application. Other applications not tested. Recommended Dilution: Western Blot: 1-10ug/ml (ECL). ELISA: 1:10,000-1:100,000 using 50-100ng of control peptide/well. Optimal dilutions to be determined by the researcher. Control Peptide: N0538-10: NBC3, Human (HCO3 Cotransporters 3) Storage and Stability: May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
