Rabbit Anti-Mouse FMC63 scFv Monoclonal Antibody (R19M), PE (100 tests)

Rabbit Anti-Mouse FMC63 scFv Monoclonal Antibody (R19M), PE (100 tests)


High affinity rabbit monoclonal antibody specifically binding to the anti-CD19 scFv that was derived from the FMC63. Its robust specificity and sensitivity (1:100,000) allows this antibody to be a perfect tool for flow cytometry and other immunostaining applications.


The rabbit monoclonal antibody R19M specifically binds to the scFv region of a CD19-specific mouse monoclonal antibody (mAb, clone FMC63). CD19 antigen is a B-cell specific cell surface antigen, which is expressed in all B-cell lineage malignancies and normal B-cells. The scFv region of FMC63 has been used to develop CD19-specific chimeric antigen receptor (CAR) T cells utilized in clinical trials.

FACS Protocol 

  • Reagents Required 
    • Phosphate Buffered Saline (PBS with a pH ~7.4).  
    • FACS Buffer (PBS containing 2% of BSA).  
    • Rabbit Anti-Mouse FMC63 scFv Monoclonal Antibody (R19M), PE (100 tests) 
  • Preparation of Reagents 
    • Rabbit Anti-Mouse FMC63 scFv Monoclonal Antibody (R19M), PE (100 tests) 
      • Protein must be diluted before use for FACS. 
      • Dilute the protein at a dilution of 1:100 in FACS buffer. 
  • Staining Protocol 
  1. Harvest the cells from source and wash the cells once using FACS buffer. 
  2. Perform a cell count and a cell viability count. Cell viability must be ≥ 95% with a cell number above 2×105 live cells. 
  3. In a round-bottom test tube, resuspend cells in 100 µL of diluted Rabbit Anti-Mouse FMC63 scFv Monoclonal Antibody (R19M), PE for 30 min at 4°C. 
  4. Wash the mixture of cells and antibody 3 times by centrifuge using FACS buffer. 
  5. Resuspend the stained cells in 200 µL PBS per cell sample.  
  6. Transfer the stained cell into a desired flow tube for analyzation on desired Flow Cytometer. The recommended acquisition rate is >10,000 events. 

Product Notices

  • Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  • Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
