Anti-Annexin 5 Antibody

Raised in rabbits against the Annexin 5 calcium-dependent phospholipid-binding protein, this unconjugated polyclonal reagent from Antibodies.com is supplied at 1 mg/ml in PBS with 0.1% Sodium Azide and 50% Glycerol. Validated for Western Blot (WB) and Immunohistochemistry (IHC), it recognizes endogenous Annexin 5 in human, mouse, and rat samples, supporting studies of apoptosis regulation, membrane repair dynamics, placental trophoblast biology, and anticoagulant signaling pathways where Annexin 5 acts as a vascular probe. The 100 µl liquid aliquot is delivered as an unconjugated primary antibody compatible with downstream labeling using HRP, biotin, or fluorophore conjugates selected by the user. Investigators commonly deploy it to track Annexin 5 redistribution during phosphatidylserine externalization, to characterize cytotrophoblast and syncytiotrophoblast differentiation, and to examine thrombin-thrombomodulin interactions in vascular injury models. For storage, aliquot the vial upon arrival and freeze at -20 °C in working volumes, avoiding repeated freeze-thaw cycles to preserve antigen-binding activity; the 50% glycerol cryoprotectant helps stabilize the protein during cold storage.
