Product details:
Human Annexin A1 ELISA Kit (ab267808) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Annexin A1 protein in cell lysate. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Annexin A1 with 0.16 ng/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Annexin A1, also known as lipocortin I, annexin I, chromobindin-9, and calpactin II, belongs to the annexin family of calcium-dependent phospholipid-binding proteins. It mimics the effect of steroids, mediates anti-inflammatory activity and is a potent inhibitor of phospholipase A2 activity. Annexin A1 regulates neutrophil extravasation by interacting with the formyl peptide receptor and triggers different signaling pathways.

Annexin A1 also known as ANXA1 or annexin 1 is a multifunctional protein with a molecular mass of approximately 37 kDa. This protein belongs to the annexin family and is distributed widely in various tissue types including the central nervous system respiratory system and immune cells. Annexin A1 functions by binding to phospholipids in a calcium-dependent manner influencing membrane-related processes and signal transduction. Its expression can be examined using techniques like annexin A1 immunohistochemistry and annexin A1 ELISA to study protein localization and concentration.
Biological function summary
Annexin A1 is involved in modulating inflammatory responses and cell proliferation. It acts as a mediator in the resolution of inflammation by promoting apoptotic cell clearance and regulating leukocyte migration. Annexin A1 participates in complex interactions often associating with cell membrane phospholipids to exert its effects. It contributes significantly to cell adhesion migration and intracellular signaling events which are important for maintaining homeostasis and proper immune function.
Pathways
Annexin A1 plays a significant role in the glucocorticoid signaling pathway and the formation of the cytoskeleton. It interacts with proteins like lipocortin 1 and phospholipase A2 impacting processes such as arachidonic acid metabolism and cytoskeletal reorganization. These interactions underline annexin A1's involvement in regulating inflammation and maintaining cellular architecture linking it to cellular processes that govern stress responses and cell movement.
Annexin A1 exhibits relevance to inflammatory diseases and cancer. It has been implicated in conditions such as asthma where it modulates inflammatory cell recruitment and activation. In cancer especially in breast cancer annexin A1 influences tumor progression by interacting with proteins like COX-2 affecting tumor cell invasion and metastasis. The protein's role in these conditions highlights its potential as both a biomarker and therapeutic target helping in understanding disease mechanisms and developing treatment strategies.
