primers of human housekeeping gene

[Maggi Burton]

     Hello,
       I am looking for some primers of human housekeeping gene that I
could use to realise RT-PCR. The expression fo these genes has to be
unchanged after exposure of human endothelial cells under hypoxia. I know
for example that GAPDH
gene expression is affected by hypoxia. If anybody has some suggestions, I
would be very pleased.
       Thank you,
