PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 is produced via site-specific conjugation of PE to Monoclonal Anti-FMC63 Antibody, Mouse IgG1 under optimal conditions with a proprietary technology.
We carry another premium grade PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (FM3-PY54G0), produced with the same production process but under more rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. It is designed for cell isolation and cell culture applications in the early preclinical stage.

产品数据图
活性（Bioactivity）-FACS
5e5 of anti-CD19 CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-PY54A2) and isotype control antibody respectively. PE signal was used to evaluate the binding activity (QC tested).
Protocol活性（Bioactivity）-FACS
Binding activity of the PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 before and after adding 0.03% Proclin was evaluated in the above FACS analysis. The result shows that PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-PY54A2) and PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Cat. No. FM3-HPY53) have the same binding activity against anti-CD19 CAR-293 cells.
Protocol活性（Bioactivity）-FACS
Non-specificity of PE-Labeled Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Y45) (Cat. No. FM3-PY54A2) binding to CD3+ cells present in human PBMC. Human PBMCs were simultaneously stained with FITC-labeled anti-CD3 antibody and PE-Labeled Monoclonal Anti-FMC63 scFv Antibody, Mouse IgG1 (Y45) (2 μL of the antibody stock solution corresponds to labeling of 5e5 cells in a final volume of 100 µL), washed and then analyzed with FACS. Both FITC and PE positive signals was used to evaluate the non-specific binding activity to human CD3+ cells (QC tested).

CAR阳性表达率检测（Evaluation of CAR expression）
FACS Analysis of Non-specific binding to Human whole blood
Non-specificity of PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (Site-specific conjugation) (0.03% Proclin) (Cat. No. FM3-PY54A2) binding to CD3+ cells present in human whole blood. 100 μl of human whole blood were simultaneously stained with APC/Cyanine7 anti-human CD3 Antibody and PE-Labeled Monoclonal Anti-FMC63 Antibody, Mouse IgG1 (Y45) (2 μL of the antibody stock solution in a final volume of 100 µL), compared with isotype control antibody and positive control antibody. Both APC/Cyanine7 and PE positive signals was used to evaluate the non-specific binding activity to human CD3+ cells.
