Anti-MMRN1 Antibody

Multimerin 1 (MMRN1) is a large, multimeric glycoprotein stored in platelet alpha-granules and the Weibel-Palade bodies of endothelial cells, where it serves as a carrier for coagulation factor V and contributes to platelet adhesion at sites of vascular injury. This rabbit polyclonal antibody from Antibodies.com targets the human MMRN1 protein and is supplied as 100 µl of liquid at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, ready to load directly into western blot, immunohistochemistry, and immunofluorescence workflows.

Validated for human reactivity, the unconjugated reagent supports studies in megakaryocyte biology, vascular biology, and the coagulation cascade, where MMRN1 expression serves as a marker of platelet and endothelial lineage. The polyclonal format provides recognition of multiple epitopes across the MMRN1 protein, which is useful when probing fixed tissue sections by IHC or imaging cultured endothelial cells by IF. For best results, aliquot the antibody upon arrival and store at -20 °C to preserve activity across repeated freeze-thaw cycles, and protect from light during handling to maintain the integrity of the conjugate-free formulation.
