The Rituximab antibody is a genetically engineered chimeric murine/human monoclonal antibody. It is directed against the CD20 antigen which found on the surface of normal and malignant B lymphocytes. The antibody is an IgG kappa immunoglobulin containing murine light- and heavy chain variable region sequences and human constant region sequences. Rituximab is composed of two heavy chains of 451 amino acids and two light chains of 213 amino acids (based on cDNA analysis) and has an approximate molecular weight of 145 kD. Rituximab has a binding affinity for the CD20 antigen approximately 8.0 nM. Rituximab is a sterile, clear, colorless, preservative-free liquid concentrate for intravenous (IV) administration.
