电泳（SDS-PAGE）
FITC-Labeled Anti-Rituximab Antibody, Mouse IgG1 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
Immobilized Rituximab at 2 μg/mL (100 μL/well) can bind FITC-Labeled Anti-Rituximab Antibody, Mouse IgG1 (Cat. No. RIB-FY35c) with a linear range of 0.01-0.3 μg/mL (QC tested).
Protocol
活性（Bioactivity）-FACS
2e5 of Anti-CD20 (Rituximab) CAR-293 cells were stained with 100 μL of 3 μg/mL of FITC-Labeled Anti-Rituximab Antibody, Mouse IgG1 (Cat. No. RIB-FY35c) and isotype control antibody respectively. FITC signal was used to evaluate the binding activity (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
