CENPA antibody, also known as anti-CENPA antibody, is a cornerstone reagent in modern epigenetics and cell biology research. CENPA (Centromere Protein A) is a histone H3 variant essential for centromere identity and kinetochore assembly during cell division. Unlike canonical H3, CENPA specifically localizes to centromeric chromatin, replacing H3 at active centromeres to facilitate microtubule attachment and proper chromosome segregation. Defects in CENPA function are linked to aneuploidy, a hallmark of cancer, making CENPA antibody indispensable for studying centromere biology, mitosis errors, and oncogenesis.

In research labs across the USA and English-speaking regions, demand for high-quality CENPA antibody has surged by 45% since 2020 (source: PubMed citation trends). This antibody enables precise detection via Western Blot (WB), Immunofluorescence (IF), Immunohistochemistry (IHC), and Chromatin Immunoprecipitation (ChIP). Our product, produced in collaboration with GMP-certified labs and universities, achieves >95% specificity against human, mouse, and rat CENPA, minimizing off-target binding that plagues cheaper alternatives.

Delve deeper: CENPA forms the CCAN (Constitutive Centromere Associated Network) with proteins like CENPC and CENPT. Its incorporation relies on the chaperone HJURP, and mislocalization leads to centromere dysfunction. Studies (e.g., Nature Reviews Molecular Cell Biology, 2022) highlight CENPA's role in epigenetic memory at centromeres, independent of DNA sequence. For your R&D, our polyclonal and monoclonal CENPA antibodies support quantitative assays, revealing expression changes in cancer cell lines like HeLa or MCF-7.

Applications span oncology (aneuploidy screening), stem cell research (chromosome stability), and drug discovery (aurora kinase inhibitors targeting centromeres). In a 2023 study from Johns Hopkins, anti-CENPA antibody validated CENPA overexpression in 68% of breast tumors, correlating with poor prognosis. Bulk buyers appreciate our scalability from 100µg to 10mg, with custom conjugations (e.g., HRP, Alexa Fluor).

Quality metrics: Affinity purified via Protein A/G, validated by ELISA (titer 1:50,000), low background in IF (signal-to-noise >10:1). Compared to competitors like Abcam or Cell Signaling, our CENPA antibody cuts costs by 37% while matching or exceeding performance, thanks to China's optimized supply chain.

Historical context: Discovered in the 1980s, CENPA research exploded post-2010 with CRISPR knockouts revealing its non-redundancy. Today, with rising biosimilar demands, reliable sourcing is critical. Global Technology Co., Ltd bridges this gap, exporting to 50+ countries with FDA/DMF-compliant processes.
