|Application ||FC, E|
|Purification||Purified IgG prepared by affinity chromatography on Protein G from tissue culture supernatant|
|Immunogen||F(ab)2 fragment of Rituximab.|
|Shelf Life||18 months from date of despatch.|
|Target/Specificity||Rat anti-rituximab antibody, clone MB2A4, specifically recognizes the idiotypic determinants expressed by the rituximab chimeric monoclonal antibody. Rituximab is a therapeutic reagent directed against the human CD20 antigen expressed on the surface of B-cells.Rat anti-rituximab antibody, clone MB2A4, is specific for rituximab and does not recognize other CD20 antibodies. Clone MB2A4 has been used in ELISA assays to monitor the levels of rituximab in patient serum following therapy (Cragget al.2004andHampsonet al.2010). Clone MB2A4 has been used to detect rituximab bound to the surface of the Raji B cell line, however detection of rituximab bound in vivo to B-CLL cells has not been demonstrated. It is possible that complement deposition on rituximab opsonised cells inhibits binding of the anti-rituximab antibody to cell bound rituximab (Beumet al.2004).|
