Encoded by the CDCA8 gene on chromosome 1p34.3, this protein interacts with Aurora B kinase, INCENP, and Survivin to form a functional complex that ensures accurate mitotic progression. Borealin is essential for proper kinetochore-microtubule attachment, spindle checkpoint activation, and correction of mitotic errors, thereby safeguarding genomic stability during cell division.\u003cbr\u003e\u003cbr\u003eDuring mitosis, Borealin localizes to centromeres in metaphase and relocates to the spindle midzone during anaphase, coordinating the transition from chromosome alignment to cytokinesis. Loss of CDCA8 function results in chromosome missegregation, lagging chromatids, and multinucleation, phenotypes commonly associated with aneuploidy and cancer. Expression of CDCA8 peaks during the G2\/M phase, reflecting its cell cycle-dependent regulation. Overexpression has been documented in a range of malignancies including breast, lung, and colorectal cancers, correlating with poor prognosis and high proliferative indices.\u003cbr\u003e\u003cbr\u003eThe CDCA8 antibody is widely used in cell cycle and cancer research to detect Borealin localization and expression dynamics. Immunofluorescence analysis with this antibody reveals distinct centromeric staining during metaphase and midbody localization in late mitosis. Western blotting identifies a 35 kilodalton band corresponding to the full-length protein. Because the chromosomal passenger complex regulates essential mitotic checkpoints, the CDCA8 antibody provides a critical tool for studying mechanisms of mitotic fidelity and tumorigenesis.\u003cbr\u003e\u003cbr\u003eCDCA8 cooperates with Aurora B to phosphorylate substrates involved in spindle tension sensing and cytokinesis. Disruption of this interaction impairs CPC activity and leads to mitotic failure. Borealin's ability to bind DNA through its N-terminal domain and oligomerize via its coiled-coil region enables structural stability of the CPC. Inhibition or knockdown of CDCA8 sensitizes tumor cells to microtubule-targeting drugs, highlighting its potential as a therapeutic target. The antibody thus supports translational research exploring CPC inhibitors and mitotic checkpoint modulators in cancer therapy.\u003cbr\u003e\u003cbr\u003eIn developmental biology, CDCA8 is required for proper cell division during embryogenesis and organogenesis. The CDCA8 antibody facilitates identification of proliferating cells in rapidly dividing tissues and embryonic stem cell cultures.\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\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\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=CDCA8 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CDCA8 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=CDCA8 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/CDCA8 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CDCA8+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":53047297409389,"sku":"FY12693","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a61fd4b4-227a-4874-b552-2f2f5e4cdf57.jpg?v=1782237050","url":"https:\/\/www.ebiohippo.com\/products\/cdca8-antibody-cell-division-cycle-associated-protein-8-borealin-bha17135596","provider":"BioHippo","version":"1.0","type":"link"}
