FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: blocking of ligand binding1-4, activation of αvβ3 integrin signaling5, and immunohistochemical staining of acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse bone marrow cells

C57BL/6 mouse bone marrow cells were stained with CD61 (clone 2C9.G2) APC (filled histogram) or Armenian hamster IgG APC isotype control (open histogram). Data shown was gated on myeloid cell population.


CD61 is a 110 kD integrin β chain also known as β3 integrin or gpIIIa. It associates with the integrin αv chain (CD51) to form the vitronectin receptor. In addition, CD61 can associate with the integrin αIIb chain (CD41) to form the gpIIb/IIIa complex. CD61 is expressed on platelets, megakaryocytes, endothelium, smooth muscle, a subset of B cells, myeloid cells, osteoclasts, and mast cells. CD61, in conjunction with CD41 or CD51, mediates adhesion to fibronectin, fibrinogen, vitronectin, thrombospondin, and von Willebrand factor. Leukocyte-endothelial adhesion is mediated by the binding of αv3 integrin or vitronectin receptor to CD31 (PECAM-1).
