#171837 Microarray-Gene fold change calculation

Posted by ubuntu_man on 24 November 2014 - 12:55 AM in Macroarray and Microarray

Hi Members,


Can someone explain how to find for ex, 2 fold up or down regulated genes from micro array intensity data using only excel?


I think this question is basic and am new to this filed, but  really want to know the calculation of 'x' fold expression from intensity dataset.  


It would be helpful if you can tell me steps to do in a layman's manner.


My dataset is like,


                Control            Treated

Gene1      7.4365             8.1134

Gene2      8.6785            11.234

Gene3      9.3233            6.8965

Gene4      8.6531           14.3475
