Encoded by the CD300A gene on chromosome 17q25.1, this transmembrane glycoprotein belongs to the CD300 family of immunoglobulin-like receptors and plays a key role in maintaining immune homeostasis. CD300A contains a single extracellular Ig-like domain that recognizes phosphatidylserine and other lipids exposed on apoptotic cells, allowing immune cells to distinguish between healthy and dying cells.\u003cbr\u003e\u003cbr\u003eStructurally, CD300A possesses multiple immunoreceptor tyrosine-based inhibitory motifs (ITIMs) within its cytoplasmic tail. Upon ligand engagement, these motifs recruit phosphatases such as SHP-1 and SHP-2, which dephosphorylate signaling intermediates and suppress proinflammatory responses. This mechanism dampens activation of monocytes, macrophages, mast cells, and NK cells, preventing excessive inflammation and autoimmune reactions. CD300A thereby acts as a negative regulator of immune activation by balancing activating signals from other CD300 family members.\u003cbr\u003e\u003cbr\u003eThe CD300A antibody is widely used in immunology, inflammation, and autoimmune disease research to study inhibitory receptor signaling, immune regulation, and apoptotic cell clearance. Flow cytometry and western blot analyses detect a 35-40 kilodalton band corresponding to CD300A, while immunohistochemistry shows strong membrane staining on leukocytes and myeloid cells. This antibody supports analysis of inhibitory receptor expression and function in both innate and adaptive immune systems.\u003cbr\u003e\u003cbr\u003eAberrant CD300A expression has been implicated in autoimmune diseases, allergy, and cancer. Increased expression can suppress antitumor immunity, while reduced expression contributes to hyperinflammatory conditions. The CD300A antibody provides a valuable tool for investigating the balance between immune activation and inhibition in health and disease.\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\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\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=CD300A - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CD300A - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=CD300A - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/CD300A - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CD300A+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":53047302619501,"sku":"FY12806","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_ccd299bf-d6a3-42ec-904d-408c934c5e84.jpg?v=1782237051","url":"https:\/\/www.ebiohippo.com\/products\/cd300a-antibody-bha17135708","provider":"BioHippo","version":"1.0","type":"link"}
