Encoded by the NRXN2 gene on chromosome 11q13.1, this protein belongs to the neurexin family of cell surface receptors that mediate trans-synaptic signaling by binding postsynaptic partners such as neuroligins and LRRTMs. Neurexin 2 is expressed primarily in the brain and spinal cord, where it contributes to the assembly and maintenance of excitatory and inhibitory synapses.\u003cbr\u003e\u003cbr\u003eStructurally, Neurexin 2 exists in multiple isoforms generated by alternative promoter usage and extensive splicing, including a long alpha form and a shorter beta form. The alpha isoform contains laminin, neurexin, and sex hormone-binding globulin (LNS) domains as well as EGF-like repeats that facilitate adhesion and receptor interaction. The beta isoform retains the transmembrane and cytoplasmic PDZ-binding motifs that mediate synaptic signaling. These isoforms together ensure molecular diversity and specificity in synapse targeting and stability.\u003cbr\u003e\u003cbr\u003eThe NRXN2 antibody is widely used in neuroscience, neurodevelopmental, and molecular signaling research to study synaptic connectivity, axon guidance, and neuropsychiatric disorders. Western blot analysis detects multiple bands corresponding to the various isoforms of Neurexin 2 (ranging from 95 to 160 kilodaltons), while immunofluorescence shows punctate staining along axons and presynaptic terminals. This antibody enables characterization of neurexin distribution and expression in both developing and mature neural networks.\u003cbr\u003e\u003cbr\u003eFunctionally, Neurexin 2 regulates synapse formation by bridging pre- and postsynaptic membranes, facilitating calcium channel clustering and neurotransmitter release. Mutations or deletions in NRXN2 have been associated with autism spectrum disorder, schizophrenia, and intellectual disability, reflecting its critical role in neuronal circuit function. The NRXN2 antibody provides an essential tool for examining how neurexin-mediated adhesion and signaling shape neuronal connectivity and plasticity.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=NRXN2 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=NRXN2 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=NRXN2 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/NRXN2 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=NRXN2+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047305404781,"sku":"FY12895","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_d3784631-4c21-4df7-a478-068bd0b8a726.jpg?v=1782237054","url":"https:\/\/www.ebiohippo.com\/products\/nrxn2-antibody-neurexin-2-bha17135797","provider":"BioHippo","version":"1.0","type":"link"}
