Notes

Prepare the Sample Dilutions

Perform sample dilutions before adding the samples to the final reaction mix. Dilute the 
samples using the volumes that were calculated by the 7500 software (“Select the Sample 
Dilution Calculations tab.” on page 128).

About the

Example

Experiment

For the comparative C

T

 example experiment:

• Sample dilutions are necessary because the sample volume is limited to 10% of the 

total reaction volume in the 7500 software. Because the total reaction volume is 
50

µ

L/reaction, the sample volume is 5

µ

L/reaction.

• The stock sample concentration is 100 ng/

µ

L. After diluting the sample according to 

the Sample Dilutions Calculations table, the sample has a concentration of 
50 ng/

µ

L. Adding 5

µ

L at this concentration to the final reaction mix volume of 

50

µ

L yields a 1

✕

 concentration in the final reaction.

• The volumes calculated in the software are:

Required

Materials

• Water (to dilute the sample)

• Microcentrifuge tubes

• Pipettors 

• Pipette tips

• Sample stock

• Vortexer

• Centrifuge
