FIXATION? WHAT HAPPENS IF I FORGET TO DILUTE MY PERM BUFFER TO 1×? WHAT HAPPENS IF I USE PE OR APC-CONJUGATED SURFACE MARKERS PRIOR TO PERMEABILIZATION WITH METHANOL? WHAT HAPPENS IF I STAIN MY CELLS WITH THE SAME ANTIBODY USED FOR STIMULATION? HOW CAN I AVOID MESSY STAINING WITH COSTAINS AND SECONDARY ANTIBODIES OF THE SAME SPECIES? WHY I AM NOT SEEING NK1 1 EXPRESSION ON BALB/C MOUSE SPLENOCYTES? IS CD14 UNIVERSALLY EXPRESSED IN HUMAN AND MOUSE MONOCYTES? HOW ABOUT OTHER T AND B LINEAGE SUBSETS? WHAT HAPPENS IF YOU USE A FITC OR A488 ANTIBODY ON GFP-TAGGED CELLS? SHOULD I USE FCR BLOCK ON ALL CELLS AND WITH ALL ANTIBODIES? DO I NEED TO USE PMA, LONOMYCIN, AND MONENSIN (AND/OR BREFELDIN A) FOR DETECTION OF SECRETED CYTOKINES IN T CELLS AND MONOCYTES? CAN I ADD MY SECONDARY AND PRIMARY ANTIBODY AT THE SAME TIME TO SPEED UP AN EXPERIMENT? CAN BIOTINYLATED ANTIBODIES AND THE STREPTAVIDIN SECONDARY BE ADDED AT THE SAME TIME? DOES VOLUME MATTER WHEN SURFACE STAINING YOUR CELLS? WHAT HAPPENS IF I CAN’T RUN MY CELLS ON THE CYTOMETER ON THE SAME DAY THAT I STAIN THEM? WHAT HAPPENS IF I ACCIDENTALLY ADD THE WRONG ANTIBODY TO MY TUBE? CAN I QUICKLY WASH IT OUT AND REUSE THOSE CELLS? CAN FLOW CYTOMETRY BE USED TO COUNT CELLS? CAN THE METHOD USED TO HARVEST ADHERENT CELLS AFFECT THE ABILITY TO DETECT PROTEIN EXPRESSION BY FLOW CYTOMETRY?
