Antibodies Applications

Source of Antigen

E. coli




The antibody was raised in sheep by immunization with the recombinant Human Annexin A1.

Amino Acid Sequence

Total 355 AA. MW: 39.8 kDa (calculated). UniProtKB acc.no. P04083 (Ala2-Asn346). N-terminal His-tag (10 extra AA). Protein identity confirmed by LC-MS/MS.


Species Reactivity

Human. Not yet tested in other species.

Purification Method

Immunoaffinity chromatography on a column with immobilized recombinant Human Annexin A1.

Antibody Content

0.1 mg (determined by BCA method, BSA was used as a standard)


The antibody is lyophilized in 0.05 M phosphate buffer, 0.1 M NaCl, pH 7.2. 


Add 0.2 ml of deionized water and let the lyophilized pellet dissolve completely. Slight turbidity may occur after reconstitution, which does not affect activity of the antibody. In this case clarify the solution by centrifugation.


At ambient temperature. Upon receipt, store the product at the temperature recommended below.


The lyophilized antibody remains stable and fully active until the expiry date when stored at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles and store frozen at -80°C. Reconstituted antibody can be stored at 4°C for a limited period of time; it does not show decline in activity after one week at 4°C.

Quality Control Test

Indirect ELISA – to determine titer of the antibody SDS PAGE – to determine purity of the antibody BCA - to determine quantity of the antibody


This product is for research use only.


Research topic

Apoptosis, Atherosclerosis, Autoimmunity, Cardiovascular disease, Diabetology - Other Relevant Products, Immune Response, Infection and Inflammation, Neural tissue markers, Oncology, Renal disease, Neurodegenerative disease


Annexin A1 binds phospholipids and up to four calcium ions. It supports membrane fusion and takes part in exocytosis. It controles phospholipase A2 activity.
