Annexin VI Antibody IHC Staining of Human Lung Cancer Tissue. Immunohistochemical analysis of FFPE human lung cancer tissue using ANXA6 Polyclonal Antibody. Brown DAB staining is visible along cellular boundaries and within portions of the cytoplasm, particularly among cells surrounding the alveolar spaces. Heat-induced epitope retrieval was performed by steaming sections in pH 8 EDTA buffer for 20 minutes, followed by cooling before staining.
Annexin VI Antibody IHC Staining of Human Thyroid Cancer Tissue. Immunohistochemical analysis of FFPE human thyroid cancer tissue using ANXA6 Polyclonal Antibody. Brown DAB staining is present in the epithelial cells lining glandular structures, with cytoplasmic and peripheral cellular staining visible against the blue hematoxylin counterstain. Heat-induced epitope retrieval was performed by steaming sections in pH 8 EDTA buffer for 20 minutes, followed by cooling before staining.
Annexin VI Antibody IHC Staining of Rat Colon Tissue. Immunohistochemical analysis of FFPE rat colon tissue using ANXA6 Polyclonal Antibody. Brown DAB staining is distributed among epithelial cells of the colonic glands, with additional staining visible in portions of the surrounding tissue. Heat-induced epitope retrieval was performed by steaming sections in pH 8 EDTA buffer for 20 minutes, followed by cooling before staining.
Annexin VI Antibody IHC Staining of Mouse Lymph Tissue. Immunohistochemical analysis of FFPE mouse lymph tissue using ANXA6 Polyclonal Antibody. Brown DAB staining is visible in scattered cells and cellular regions throughout the lymphoid tissue, against a predominantly blue hematoxylin counterstain. Heat-induced epitope retrieval was performed by steaming sections in pH 8 EDTA buffer for 20 minutes, followed by cooling before staining.
Annexin VI Antibody Western Blot Analysis of Human, Rat and Mouse Lysates. Western blot analysis using ANXA6 Polyclonal Antibody at 0.5 ug/ml. Lane 1: human placenta; lane 2: human Jurkat cells; lane 3: human HeLa cells; lane 4: human HepG2 cells; lane 5: rat liver; lane 6: rat lung; lane 7: mouse liver; lane 8: mouse lung. Immunoreactive bands are detected in the approximately 67-76 kDa region, consistent with the expected molecular weight range of annexin A6.
Annexin VI Antibody Flow Cytometry Analysis of Human HL60 Cells. Flow cytometric analysis of fixed and permeabilized human HL60 cells using ANXA6 Polyclonal Antibody at 1 ug per 10^6 cells following blocking with goat serum. The red histogram represents cells alone, the green histogram represents the isotype control, and the blue histogram represents antibody-stained cells. The rightward shift of the blue population relative to both controls indicates detectable intracellular ANXA6 immunoreactivity.
Annexin VI Antibody Western Blot Validation in HEK293 Wild-Type and ANXA6 Knockout Cells. Western blot analysis of human HEK293 wild-type (WT) and ANXA6 knockout (KO) whole-cell lysates using ANXA6 Polyclonal Antibody at 0.5 ug/ml. Lane 1 contains WT lysate and lane 2 contains ANXA6 KO lysate, with 30 ug of total protein loaded per lane under reducing conditions. An immunoreactive band at approximately 68-76 kDa is detected in the WT sample and is absent or markedly reduced in the KO sample, supporting antibody specificity for ANXA6. GAPDH serves as the loading control.

Description

Annexin VI Antibody / ANXA6 Polyclonal Antibody targets annexin A6 (ANXA6), a member of the annexin family of calcium-dependent phospholipid-binding proteins. Also known as annexin VI, this protein is distinguished from most other annexins by its eight conserved annexin repeats, organized into two homologous core domains. These structural features allow ANXA6 to associate with negatively charged membrane phospholipids in response to changes in intracellular calcium concentrations. The protein participates in membrane organization, vesicular transport, cytoskeletal interactions, and the regulation of cellular signaling pathways.

ANXA6 contains two annexin core modules connected by a flexible linker, an arrangement that supports interactions with membrane surfaces and contributes to membrane organization. Although primarily cytoplasmic, annexin A6 can redistribute to the plasma membrane and intracellular membrane compartments in response to calcium signaling. Its membrane-associated functions include regulation of endocytosis, endosomal trafficking, cholesterol transport, and the organization of specialized lipid domains. ANXA6 also interacts with cytoskeletal components, helping coordinate membrane dynamics with changes in cellular architecture.

Beyond its structural functions, annexin A6 influences several intracellular signaling pathways. It has been implicated in the regulation of Ras-MAPK signaling, calcium homeostasis, and the localization of signaling complexes at membrane surfaces. Through these activities, ANXA6 can influence cell proliferation, differentiation, migration, and responses to extracellular stimuli. Its regulatory effects are context dependent and reflect interactions with membrane lipids, signaling proteins, and cytoskeletal components. Annexin A6 has also been investigated in cancer biology, where altered expression and localization may contribute to differences in tumor cell behavior.

The relationship between ANXA6, membrane lipid composition, and intracellular signaling highlights its importance in maintaining cellular organization and coordinating responses to environmental changes. Its involvement in cholesterol trafficking and endosomal transport further connects membrane dynamics with metabolic regulation and signal transduction. Research using Annexin VI Antibody can help characterize ANXA6 expression and distribution in relation to these biological processes, particularly the calcium-dependent membrane interactions that distinguish annexin A6 from other members of the annexin protein family.

Application Notes

Optimal dilution of the Annexin VI Antibody / ANXA6 Polyclonal Antibody should be determined by the researcher.

Immunogen

A human partial recombinant protein corresponding to amino acids N395-L665 was used as the immunogen for the Annexin VI antibody.
