Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is ≤ 0.5 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes:
Additional reported applications (for the relevant formats) include: blocking of ligand binding1-4, activation of αv β3 integrin signaling5, and immunohistochemical staining of acetone-fixed frozen sections. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm sterile-filtered) is recommended for functional assays (Cat. No. 104310).

C57BL/6 mouse bone marrow cells stained with purified 2C9.G2, followed by anti-Armenian hamster IgG FITC
Description:
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 αv/β3 integrin or vitronectin receptor to CD31 (PECAM-1). The 2C9.G2 antibody reacts with mouse and rat CD61, and is able to block ligand binding.
