Report
活性（Bioactivity）-ELISA
Immobilized Rituximab at 1 μg/mL (100 μL/well) can bind Anti-Rituximab Antibody (Cat. No. RIB-Y35c) with a linear range of 0.2-6 ng/mL (QC tested).
Protocol
Immobilized Rituximab at 2 μg/mL, add increasing concentrations of Anti-Rituximab Antibody (Cat. No. RIB-Y35c) in the 10% human serum and then add Anti-CD20, Human IgG1 at 5 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 100 ng/mL (QC tested).
Protocol
背景（Background）
Rituxan is a genetically engineered chimeric murine/human monoclonal antibody directed against the CD20 antigen found on the surface of normal and malignant B lymphocytes. The antibody is an IgG1 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, Anti-Rituximab Antibodies (RIB-Y35c) is the monoclonal antibody of Rituximab expressed with human HEK293 cells.
