电泳(SDS-PAGE)
Anti-Rituximab Antibody (AY36) on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
活性(Bioactivity)-ELISA
Anti-Rituximab Antibodies bridging ELISA for Anti-Drug Antibody (ADA) assay development.Immobilized rituximab at 1 µg/mL, add increasing concentrations of Anti-Rituximab Antibody (AY36) (Cat. No. RIB-Y36, 10% human serum) and then add biotinylated rituximab at 2 µg/mL. Detection was performed using HRP-conjugated streptavidin with a sensitivity of 9.7 ng/mL (QC tested).
Protocol
Demonstration of the specificity of Anti-Rituximab Antibody (AY36) (Cat. No. RIB-Y36) to the rituximab.
Protocol
活性(Bioactivity)-MSD
Anti-Rituximab Antibodies bridging MSD for Anti-Drug Antibody (ADA) assay development. Added the mix solution (biotinylated Rituximab at 5 µg/mL, SULFO-Rituximab at 5 µg/mL and increasing concentrations of Anti-Rituximab Antibody (AY36) (Cat. No. RIB-Y36, 100% human serum). Detection was performed using MSD Assay with a sensitivity of 0.97 ng/mL.
活性(Bioactivity)-SPR
Anti-Rituximab Antibody (AY36) (mouse IgG1, Cat. No. RIB-Y36) captured on CM5 chip via anti-mouse antibodies surface, can bind human rituximab with an affinity constant of 0.01 nM.
Protocol
活性(Bioactivity)-FACS
FACS analysis shows that the binding of rituximab to 293F overexpressing CD20 was inhibited by increasing concentration of Anti-Rituximab Antibody (AY36) (Cat. No. RIB-Y36). The concentration of rituximab used is 10 ng/ml. The IC50 is 0.025 μg/ml (Routinely 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
