Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence in the middle region of human Annexin IV, different from the related mouse and rat sequences by three amino acids.
- Molecular weight context: reported MW: 36 kDa; calculated MW: 35883 MW
- Reactivity: Human,Mouse,Rat
- Applications: Flow Cytometry, IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Annexin A4; Annexin A4. ANXA4 (Annexin A4), also known as ANX4, is a protein that in humans is encoded by the ANXA4 gene. It belongs to the annexin family of calcium-dependent phospholipid binding proteins. By PCR analysis of somatic cell hybrids and in situ hybridization with a cDNA probe, the human ANXA4 gene is mapped to chromosome 2p13. Isolated from human placenta, ANXA4 encodes a protein that has possible interactions with ATP, and has in vitro anticoagulant activity and also inhibits phospholipase A2 activity. And ANXA4 is almost exclusively expressed in epithelial cells. Functional note: Calcium/phospholipid-binding protein which promotes membrane fusion and is involved in exocytosis. . Reported localization: Nucleus. Expression/tissue context: Expressed at high levels in lung, placenta and thymus and at lower levels in ovary, intestine and brain.

Common research applications
- Western blotting: compare relative ANXA4 (Annexin A4) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of ANXA4 (Annexin A4) across tissue regions and cell types using matched controls.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
