Description

Annexin A7, also known as synexin, plays a critical role in calcium-dependent membrane fusion events and has been implicated in diverse cellular processes including exocytosis, apoptosis, and tumor suppression. Research has linked ANXA7 dysregulation to various cancers, making it a compelling target for investigators studying membrane dynamics, calcium signaling pathways, and oncogenic mechanisms.

This recombinant monoclonal antibody against human ANXA7 offers the reproducibility that demanding experimental workflows require. Generated through recombinant technology with a defined sequence, clone 7D6 delivers the lot-to-lot consistency essential for longitudinal studies and quantitative comparisons across experiments. The rabbit IgG format, produced against a synthetic peptide derived from human ANXA7, ensures specificity while the affinity-chromatography purification yields a reagent ready for sensitive detection methods.

Validation studies demonstrate reliable performance in both immunofluorescence and flow cytometry applications using SH-SY5Y neuroblastoma cells. Immunofluorescence staining at dilutions between 1:50 and 1:200 reveals clear cytoplasmic localization patterns when counter-stained with DAPI, while flow cytometry analysis shows distinct positive population shifts compared to isotype controls. The successful detection in SH-SY5Y cells makes this antibody particularly relevant for neuroscience research, where ANXA7's role in neuronal calcium homeostasis and membrane repair continues to attract investigation.

The unconjugated format provides flexibility for researchers to pair this antibody with their preferred secondary detection systems, whether fluorophore-conjugated antibodies for microscopy or enzyme-linked reagents for other applications. For investigators exploring annexin biology, calcium-dependent signaling, or neuroblastoma cell biology, this antibody delivers the technical reliability needed to advance mechanistic understanding of ANXA7 function.

  4. data reveal that high UBE3C expression contributes to glioma progression by ubiquitination and degradation of ANXA7, and thus presents a novel and promising target for glioma therapy. PMID: 26067607
  5. High annexin A7 expression is associated with poor differentiation in gastric cancer patients, and it may be a predictor for lymphatic metastasis. PMID: 25400735

  24. Decreased ANXA7 expression was mostly associated with high invasive potential in multiple tumors. The lymph node metastases from different sites (including prostate and breast) had decreased ANXA7 expression. PMID: 17708571
