This product is stable after storage at:
Anti-Rituximab Antibodies (recommended for PK/PD) on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Detection of rituximab by bridging ELISA in serum. Immobilized Anti-Rituximab Antibodies (Cat. No. RIB-Y37) at 2 μg/mL, add increasing concentrations of rituximab (10% human serum) and then add Biotinylated Anti-Rituximab Antibodies (Cat. No. RIB-BY35) at 1 μg/mL. Detection was performed using HRP-conjugated streptavidin with a sensitivity of 1 ng/mL.
Demonstration of the specificity of Anti-Rituximab Antibodies (Cat. No. RIB-Y37) to the rituximab.
FACS analysis shows that the binding of rituximab to 293F overexpressing CD20 was inhibited by increasing concentration of Anti-Rituximab Antibodies (Cat. No. RIB-Y37). The concentration of rituximab used is 10 ng/ml. The IC50 is 0.019 μg/ml (Routinely tested).
