Anti-LNPEP/IRAP Antibody, clone 1G23 ZooMAb^® Rabbit Monoclonal

Leucyl-cystinyl aminopeptidase (UniProt: Q9UIQ6; also known as EC:3.4.11.3, Cystinyl aminopeptidase, Insulin-regulated membrane aminopeptidase, Insulin-responsive aminopeptidase, IRAP, Oxytocinase, OTase, Placental leucine aminopeptidase, P-LAP) is encoded by the LNPEP (also known as OTASE) gene (Gene ID: 4012) in human. LENPEP/IRAP is a zinc-dependent aminopeptidase that cleaves vasopressin, oxytocin, dynorphin A and other peptide hormones and is involved in the inactivation of neuronal peptides. It is a single-pass type II membrane protein with a cytoplasmic domain (aa 1-110), a transmembrane domain (aa 111-131), and a large extracellular domain (aa 132-1025). It is highly expressed in placenta, heart, kidney, and small intestine. Lower levels are detected in neuronal cells, skeletal muscle, spleen, liver, testes, and colon. In the brain tissue only a membrane-bound form is reported. It resides in intracellular vesicles together with GLUT4. and can then translocate to the cell surface in response to insulin and/or oxytocin. Cleavage of membrane-bound LENPEP/IRAP between residues 154-155 generates a pregnancy serum form that plays a role in maintaining homeostasis during pregnancy. Three isoforms of LENPEP/IRAP 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.

Clone 1G23 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Leucyl-cystinyl aminopeptidase (LNPEP). It targets an epitope within 16 amino acids from the cytoplasmic domain.

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.
