Clone 1E14 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects GPR37. It targets an epitope within 19 amino acids from the first extracellular domain within the N-terminal half.

Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

Prosaposin receptor GPR37 (UniProt: O15354; also known as Endothelin B receptor-like protein 1, ETBR-LP-1, G-protein coupled receptor 37, Parkin-associated endothelin receptor-like receptor, PAEL-R, PAELR) is encoded by the GPR37 gene (Gene ID: 2861) in human. GPR37 is an orphan G-protein coupled receptor that is exclusively expressed in the nervous system. It is a multi-pass membrane protein with seven transmembrane domains and is synthesized with a signal peptide (aa 1-26) that is subsequently cleaved off to produce the mature protein. The mature GPR37 is exported from the endoplasmic reticulum to the cell surface, where its long extracellular N-terminus is rapidly and constitutively cleaved by metalloproteinases. It serves as a receptor for the neuroprotective and glioprotective factor prosaposin Ligand binding is shown to induce its endocytosis, followed by an ERK phosphorylation cascade. It is reported to mediate the control of oligodendrocyte differentiation. GPR37 expression and mRNA expression are significantly increased in substantia nigra of sporadic Parkinson s disease cases. The level of ecto-GPR37 peptides is also significantly increased in the cerebrospinal fluid of Parkinson s disease subjects, but not in Alzheimer s disease. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

KLH-conjugated linear peptide corresponding to 19 amino acids from the first extracellular domain within the N-terminal half of human GPR37.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
