Tired of disappearing marker pens? Tape them under your workbench. Better yet, tape only the lid so that you can easily pull the marker off and slip it back to its hiding place once you’re done.
If you are setting up multiple PCR reactions in a 96-well plate, the easiest way to keep track when dispensing cDNA is to match the layout of the plate with the layout of your pipette tips. No more panicking if you have forgotten which wells already have cDNA!
