Annexin A1: may have potential anti-inflammatory activity. 

Annexin V: apoptotic marker, identify the integrity of cell membrane (used for FC)

Annexin A1 belongs to the annexin family of Ca²⁺-dependent phospholipid-binding proteins that have a molecular weight of approximately 35,000 to 40,000 Dalton and are preferentially located on the cytosolic face of the plasma membrane. Annexin A1 protein has an apparent relative molecular mass of 40 kDa with phospholipase A2 inhibitory activity.
