Housekeeping Genes

[Chris Herbert]

Hi there

I am currently carrying out some Real-Time PCR experiments using a Roche 
Lightcycler on tumour and non-tumour tissue samples. As this is a very 
sensitive technique I require reliable housekeeping genes to use as 
internal standards for these experiments.  It has been suggested that I use 
GAPDH, but I am reluctant to use this as it has recently been suggested 
that GAPDH levels increase dramatically in times of cellular stress.  I 
have used Beta-Actin as an internal control for my experiments so far but 
wish to validate my results by checking that levels of cDNA are normalised 
using a second or third housekeeping gene.

Can anybody suggest other housekeeping genes that I can use?

Many thanks for your help.

Chris.
