<prompt> Answer this question truthfullyCould you please provide some information about Abciximab?  <response>: <reason> Abciximab, ReoPro , is the Fab fragment of the chimeric human-murine monoclonal antibody 7E3. Abciximab binds to the glycoprotein GP IIbIIIa receptor of human platelets and inhibits platelet aggregation. The chimeric 7E3 antibody is produced by continuous perfusion in mammalian cell culture. The 47,615 dalton Fab fragment is purified from cell culture supematant by a series of steps involving specific viral inactivation and removal procedures, digestion with papain and column chromatography. ReoPro is a clear, colorless, sterile, non-pyrogenic solution for intravenous IV use. Each single use vial contains 2 mgmL of Abciximab in a buffered solution pH 7.2 of 0.01 M sodium phosphate, 0.15 M sodium chloride and 0.00 1 polysorbate 80 in Water for Injection. No preservatives are added.
