Anti-Sodium Antibody, Potassium, Chloride Cotransporter 1

170 kDa

The Na+/K+/Cl- Cotransporter isoform 1 (NKCC1) is involved in the transport of sodium, potassium, and chloride ions across membranes. NKCC1 mediates sodium and chloride reabsorption and plays an important role in cell volume regulation. NKCC1 is also involved in the control of normal cell proliferation, while its overexpression results in apparent cell transformation, in a manner similar to some protooncogenes (Panet, 1999). NKCC1 is inhibited by bumetanide and is also referred to as the bumetanide-sensitive sodium-(potassium)-chloride cotransporter 1. Inhibition of NKCC1 activity by bumetanide decreases the high-[K+]o-mediated uptake of Cl , blocks astrocyte swelling, and leads to cell shrinkage under isotonic conditions in cells such as retinal pigment epithelia, ventricular myocytes, and vascular endothelial cells (Russell, 2000; Su, 2002). NKCC1 could contribute to an overload of intracellular Na+, K+, and Cl- and cell swelling in conditions such as cerebral ischemia (Yan, 2001). NKCC1 is expressed in multiple tissues with the amount of mRNA expression varying as much as thirty-fold. It is highly expressed in neurons and astrocytes through-out the brain and has been implicated in ischemic necrotic cell death.

A 22 amino acid peptide sequence near the C-terminus of rat NKCC1. (Moore-Hoon et al. 1998; Delpire et al. 1994; Payne et al. 1995; Isering et al. 1997; Mount et al. 1998).

Detect Sodium using this Anti-Sodium Antibody, Potassium, Chloride Cotransporter 1 validated for use in ELISA, IH & WB.

Immunohistochemistry:
It is recommended that the antibody be tried at 2-20 µg/mL on paraformaldehyde fixed tissue.

ELISA:
0.5-1.0 µg/mL of a previous lot was used with 1 µg/mL control peptide per well.

Optimal working dilutions must be determined by the end user.
