Recommended Assay Procedures: Recommended Assay Procedures Recommended Assay Procedure for Bioimaging: http://www.bdbiosciences.com/support/resources/protocols/ceritifed_reagents.jsp 1. Seed ~10,000 cells in appropriate culture medium in a BD Falcon™ 96-well Imaging Plate (Cat. No. 353219) and culture overnight. 2. Remove the culture medium from the wells and fix the cells by adding 100 µl of fresh 3.7% Formaldehyde in PBS or BD Cytofix™ Fixation Buffer (Cat. No. 554655) to each well and incubate for 10 minutes at room temperature (RT). 3. Remove the fixative from the wells, and permeabilize the cells using either cold methanol or Triton™ X-100. a. Add 100 μl of -20°C 90% methanol or -20°C BD Phosflow™ Perm Buffer III (Cat. No. 558050) to each well and incubate (5 min, RT). OR b. Add 100 µl of 0.1% Triton™ X-100 (Sigma-Aldrich Cat. No. X-100) to each well and incubate (5 min, RT). 4. Remove the permeabilizer from the wells, and wash wells twice with 100 μl of 1× PBS. 5. Remove the PBS and block the cells by adding 100 μl of blocking buffer, eg, BD Pharmingen™ Stain Buffer (FBS) (Cat. No. 554656) or 3% FBS in 1× PBS to each well and incubate (30 min, RT). 6. Meanwhile, put 5 ul (1 test size) Bioimaging Certified fluorescent antibodies into 45 ul of Stain Buffer; protect from light. 7. Remove the blocking buffer and add 50 μl of prepared fluorescent antibody per well and incubate (60 min, RT), protect from light. 8. Remove the fluorescent antibody and wash the wells three times with 100 μl of 1× PBS. 9. Remove the PBS and counterstain the nuclei by adding 100 µl of a 2 µg/ml solution of Hoechst 33342 (Cat. No. 561908) in 1× PBS to each well at least 15 minutes before imaging. 10. View and analyze the cells using an appropriate imaging instrument. Recommended filters for the BD Pathway™ Instruments are: Instrument Excitation Emission Dichroic BD Pathway™ 855 488/10 515 LP Fura/FITC BD Pathway™ 435 482/35 536/40 FF506
Product Notices: Product Notices This reagent has been pre-diluted for use at the recommended Volume per Test when following the Recommended Assay Procedure. A Test is typically ~10,000 cells cultured in a well of a 96-well imaging plate. An isotype control should be used at the same concentration as the antibody of interest. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
