Brief Description & Uses

100 g of monoclonal antibody reactive against the 52 kDa F1F0 ATP synthase (Complex V) β subunit. MS503 also labels β in immunocytochemical applications. Isolated mitochondria are available from several species for use as control samples. To see the complete list of control samples available from MitoSciences, click here.

An important recent finding is that F1F0 is an ectopic protein in many cells and tissues in addition to its location within mitochondria. In endothelial cells F1F0 acts as an angiostatin receptor. Both synthesis and hydrolysis activity of the ectopic F1F0 are inhibited by angiostatin. The β mAb above (MS503) has been shown to act as an angiostatin mimetic and to inhibit the proliferation of endothelial cells. The anti β subunit mAb (MS503) is able to detect plasma membrane F1F0. More recently it has been reported that in liver cells this protein complex is the HDL receptor. Importantly not all cells have F1F0 on their surface; there is no reactivity of this antibody with the surface of MRC-5 fibroblast cells.
