Prepare the FITC stock solution:
 
 
1. Spin down FITC stock tube to make sure pellet is at the bottom of tube.
 
 
2. Prepare 2x FITC stock solution (500 μM) by resuspending FITC in 1 mL of 1xPBS
 
 
3. Incubate the solution at 42°C for 4 hours
 
 
4. Dilute the 2x FITC stock solution in half with 1xPBS to make a 1x FITC solution and resulting concentration of FITC stock solution 250 μM.

# Place samples on ice.
 
# At the end of sampling point need to measure samples (OD and Fl measurement), see the below for details.
 
# Record data in notebook
 
# Import data into Excel (cell measurement tab) Sheet_1 provided
 
 
== Measurement ==
 
 
It is important that use the same instrument settings that used when measuring the FITC standard curve. This includes using the sample volume (100 ul) or 1 mL sample for measurement using spectrophotometer.
 
 
Samples should be laid out according to Fig. 2. Pipette 100 µl of each sample into each well. Set the instrument settings as those that gave the best results in calibration curves (no measurements off scale). If necessary can test more than one of the previously calibrated settings to get the best data (no measurements off scale).
