---+ Microplate Reader Quick Start 1 It's always best to start from single colony picks that had been grown overnight in liquid culture to saturation. 1 A typical start culture dilution is 2:200, 1:200 or 1:250. The most diluted one (1:250) would provide the best result for measuring lag phase times. 1 Plan out which wells will contain what sample. Randomizing a bit can help average out temperature differences throughout the plate; you can use a simple "JumpTwoRowsDown-Jump#ofReplicatesToRight" algorithm for positioning each replicate in the 96-well plate. Printable 96 well plate templates are available <span style="background-color: transparent">[[http://www.cellsignet.com/media/plates/96.jpg][online]]</span><span style="background-color: transparent">. Generally, each condition should be done in quadruplicate (or triplicate depending on space concerns). DON'T FORGET TO INCLUDE MEDIA BLANKS (minimum of one!)</span> 1 Sign up and make reservation for TECAN microplate reader here [[https://tecanplatereader.skedda.com/booking][TECAN microplate]] 1 Select the appropriate type of plate for your application: black walled, clear bottom for fluorescence (white walled, clear bottom is generally for luminescence and completely clear is generally for other applications, like measuring OD600). 1 Ensure that you have adequate controls for your experiment. At the very least, have your negative control in the same media grown under the same conditions. 1 Turn on the plate reader - there is a power button in the back next to the power cord - and then turn on the Magellan software on the computer next to it. Not doing it in this order may cause the software to fail to recognize the machine. 1 Select the option that says "raw data" and eventually you will find yourself at the configuration screen. 1 Once the protocol is started an Excel worksheet will open up automatically to record the data.
