Background of Annexin A4

Annexin IV, also known as placental anticoagulant protein II, or zymogen granule membrane-associated protein, 36-KD (ZAP36), is one of the family of calcium-dependent phospholipid-binding proteins whose normal function is uncertain. Annexin IV has 45 to 59% identity with other members of the annexin family. Annexin IV gene spans 18 to 56 kb. And it is located on mouse chromosome 6 in a region of conserved synteny with human chromosome 2. Rat annexin IV is ubiquitously expressed in epithelial tissues. Zap36 associated with zymogen granule membranes in dog and rat pancreas. Human annexin IV gene is mapped to chromosome 2p13.

6 Customer Q&As for Anti-Annexin IV/ANXA4 Antibody


Does anti-Annexin IV/ANXA4 antibody PA1007-1 work on horse IHC with adrenal gland?

Verified Customer

Verified customer

Asked: 2019-08-20


Our lab technicians have not tested anti-Annexin IV/ANXA4 antibody PA1007-1 on horse. You can run a BLAST between horse and the immunogen sequence of anti-Annexin IV/ANXA4 antibody PA1007-1 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated horse samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in horse adrenal gland in IHC, you can get your next antibody for free.

Does PA1007-1 anti-Annexin IV/ANXA4 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2019-07-03


You can see on the product datasheet, PA1007-1 anti-Annexin IV/ANXA4 antibody as been tested 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 IV/ANXA4 antibody PA1007-1 for mouse tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on monkey tissues as well?

Verified Customer

Verified customer

Asked: 2019-06-27


The anti-Annexin IV/ANXA4 antibody (PA1007-1) has not been validated for cross reactivity specifically with monkey tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in monkey you can get your next antibody for free. Please contact me if I can help you with anything.
