Preparation And Storage: Preparation And Storage Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 700 under optimum conditions, and unreacted Alexa Fluor® 700 was removed.
Recommended Assay Procedures: Recommended Assay Procedures Flow cytometry: Camptothecin, an extract of the Chinese tree Camptotheca acuminata , is a potent inhibitor of topoisomerase I, a molecule required for DNA synthesis. Camptothecin has been reported to induce apoptosis in a dose dependent manner in vitro . Materials · Prepare a 1.0 mM stock solution of camptothecin (Sigma-Aldrich; Cat. No. C-9911) in DMSO. · Jurkat cell line (ATCC TIB-152), proliferating, at 1 x 10^6 cells/ml. · Either BD Cytofix/Cytoperm™ Fixation/Permeablization Kit (Cat. No. 554714) or Cytofix/Cytoperm™ solution (Cat. No. 554722) plus Perm/Wash™ buffer (Cat. No. 554723). Procedure 1. Add camptothecin (4-6 µM final concentration) per 1 x 10^6 proliferating Jurkat cells.  If desired, a control aliquot of untreated cells should also be prepared. 2. Incubate the cells for 4-6 hours at 37°C. 3. Wash the cells (camptothecin-treated and control aliquots) twice with cold PBS; then resuspend them in BD Cytofix/Cytoperm™ solution at 2 x 10^6 cells/ml. 4. Incubate the cells for 20 minutes on ice. 5. Pellet the cells, and aspirate and discard the Cytofix/Cytoperm™ solution. 6. Wash the cells twice at room temperature with 0.5 ml Perm/Wash™ buffer per 1 x 10^6 cells, and discard the supernatants. 7. Resuspend the cells in Perm/Wash™ buffer at 10 x 10^6 /ml. 8. Aliquot test samples of 1 x 10^6 cells per 100-µl test. 9. Add 5 µl antibody per test, and incubate for 30 minutes at room temperature. 10. Wash each test in 1.0 ml Perm/Wash™ Buffer and discard the supernatant. 11. Resuspend each test in 0.5 ml Perm/Wash™ Buffer and analyze by flow cytometry.
