Target description

Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (UniProt: O14745; also known as NHERF-1, Ezrin-radixin-moesin-binding phosphoprotein 50, EBP50, Regulatory cofactor of Na(+)/H(+) exchanger, Sodium-hydrogen exchanger regulatory factor 1, Solute carrier family 9 isoform A3 regulatory factor 1) is encoded by the SLC9A3R1 (also known as NHERF, NHERF1) gene (Gene ID: 9368) in human. EBP50 is a scaffold protein that connects plasma membrane proteins with members of the ezrin/moesin/radixin family and thereby helps to link them to the actin cytoskeleton and to regulate their surface expression. Its expression is observed in several tissues, including liver, kidney, pancreas, prostate, spleen, placenta, and small intestine. It contains two PDZ domains (aa 14-94 and 154-234) that are essential for its binding to multiple ligands. It is involved in the regulation of phosphate reabsorption in the renal proximal tubules. It also plays a role in the regulation of the activity and subcellular location of Na(+)/H(+) exchanger 3 (SLC9A3) and is essential for cAMP-mediated phosphorylation and inhibition of SLC9A3. It is also reported to be essential for recycling of internalized adrenoceptor β2.Mutations in SLC9A3R1 gene are known to cause hypophosphatemic nephrolithiasis, a disease characterized by decreased renal phosphate absorption, renal phosphate wasting, hypercalciuria, and osteoporosis. Two isoforms of EBP50 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

0.3 mg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
