General description
Neurofibromin (UniProt: P21359; also known as Neurofibromatosis-related protein NF-1) is encoded by the NF1 gene (Gene ID: 4763) in human. Neurofibromin is a GTPase-activating protein (GAP) that negatively regulates RAS/MAK signaling pathway by enhancing the hydrolysis of Ras-bound GTP. Hence, it can display tumor suppressor properties. Neurofibromin is widely expressed in brain, peripheral nerves, lung, colon, breast, and muscle tissues. It is primarily located in the cytoplasm and the plasma membrane of cells, with some presence in the nucleus. Neurofibromin has a Ras-GTP domain localized to amino acids 1235-1451. It also has a CRAL-TRIO domain (aa 1580-1738) that facilitates its binding to phospholipids. It binds primarily glycerophospholipids with monounsaturated C18:1 and/or C16:1 fatty acid moieties and a phosphatidylethanolamine or phosphatidylcholine head group. Six different isoforms of Neurofibromin have been described that are produced by alternative splicing. Neurofibromin has also been shown to serve as an estrogen receptor alpha (ER-a) transcriptional co-repressor through leucine/isoleucine-rich motifs, and this activity is independent of the GAP activity. Its depletion can thus cause estradiol hypersensitivity and tamoxifen agonism, which correlate with poor outcomes seen in ER+ breast cancer patients. Germline NF1 loss-of-function mutations in NF1 gene are known to cause Neurofibromatosis type I that involved tumors in the peripheral nervous system and fibromatous skin tumors. Somatic NF1 loss is also frequently detected in a wide range of tumors. Some mutations are also known to cause colorectal cancer and juvenile leukemia. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary 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.
Immunogen
KLH-conjugated linear peptide corresponding to 25 amino acids from the C-terminal region of human NF1.
Application
Quality Control Testing
Evaluated by Western Blotting in nuclear extract from U-2 OS cells.
Western Blotting Analysis: A 1:1,000 dilution of this antibody detected NF1 in nuclear extract from U-2 OS cells.
Tested Applications
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected NF1 in nuclear extract from HEK-293 cells.
Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected NF1 in human cerebral cortex tissue sections.
Affinity Binding Assay: A representative lot of this antibody bound NF1 peptide with at least ten thousand-fold (10,000X) higher affinity than with non-specific control peptide.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Biochem/physiol Actions
Clone 2N2 is a ZooMAb® recombinant rabbit monoclonal antibody that specifically detects NF1. It targets an epitope within 25 amino acids from the C-terminal region.
Physical form
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.
Preparation Note
300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
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.
