Background of Annexin A1
ANXA1, also known as lipocortin I or Annexin A1, is a protein that in humans is encoded by the ANXA1 gene. It is mapped to 9q21.13. ANXA1 belongs to a family of Ca (2+)-dependent phospholipid binding proteins which have a molecular weight of approximately 35,000 to 40,000 and are preferentially located on the cytosolic face of the plasma membrane. ANXA1 protein has an apparent relative molecular mass of 40 kDa, with phospholipase A2 inhibitory activity. Lower peptide concentrations possibly found in inflammatory situations elicit Ca (2+) transients without fully activating the mitogen-activated protein kinase pathway. This causes a specific inhibition of the transendothelial migration of neutrophils and a desensitization of neutrophils toward a chemoattractant challenge. These findings identified ANXA1 peptides as novel, endogenous FPR ligands and established a mechanistic basis of ANXA1-mediated antiinflammatory effects.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Figure 1. Western blot analysis of Annexin A1/ANXA1 using anti-Annexin A1/ANXA1 antibody (PB9127).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30ug of sample under reducing conditions.
Lane 1: human Hela whole cell lysates,
Lane 2: human K562 whole cell lysates,
Lane 3: monkey COS-7 whole cell lysates,
Lane 4: human A549 whole cell lysates,
Lane 5: human PC-3 whole cell lysates,
Lane 6: human U20S whole cell lysates,
Lane 7: rat spleen tissue lysates,
Lane 8: rat lung tissue lysates,
Lane 9: rat kidney tissue lysates,
Lane 10: rat C6 whole cell lysates.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Annexin A1/ANXA1 antigen affinity purified polyclonal antibody (Catalog # PB9127) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Annexin A1/ANXA1 at approximately 39KD. The expected band size for Annexin A1/ANXA1 is at 39KD.

Figure 2. IHC analysis of Annexin A1 using anti-Annexin A1 antibody (PB9127).
Annexin A1 was detected in a paraffin-embedded section of human tonsil tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1 μg/ml rabbit anti-Annexin A1 Antibody (PB9127) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC) (Catalog # SA1022) with DAB as the chromogen.

Question
I have a question about product PB9127, anti-Annexin A1/ANXA1 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?
Verified Customer
Verified customer
Asked: 2018-05-31
Answer
We do not recommend storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PB9127 anti-Annexin A1/ANXA1 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

We have observed staining in mouse liver. Are there any suggestions? Is anti-Annexin A1/ANXA1 antibody supposed to stain liver positively?
A. Edwards

Asked: 2018-03-27
Answer
From what I have seen in literature liver does express ANXA1. From what I have seen in Uniprot.org, ANXA1 is expressed in mouth mucosa, cervix lung, cervix carcinoma, cervix carcinoma erythroleukemia, liver, among other tissues. Regarding which tissues have ANXA1 expression, here are a few articles citing expression in various tissues:
Cervix carcinoma, Pubmed ID: 18669648, 20068231
Cervix carcinoma, and Erythroleukemia, Pubmed ID: 23186163

Question
Does PB9127 anti-Annexin A1/ANXA1 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
Verified Customer
Verified customer
Asked: 2017-08-16
Answer
It shows on the product datasheet, PB9127 anti-Annexin A1/ANXA1 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

We are currently using anti-Annexin A1/ANXA1 antibody PB9127 for rat tissue, and we are well pleased with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it true that the antibody can work on horse tissues as well?
