Does anyone know sequences for an 18S primer?
The primer would be used as a housekeeping gene.
I am working with HeLa cells to measure gene expression
18S primers: forward 5′-GATGTAGTTGCTTGGGACCCA-3′ and reverse 5′-TGGAGATAACACTCTAAGCATAACTAAAGGT-3′ (size 140 bp)
Good Luck
Imran
I am not sure that you can regard ribosomal genes as background. A more active cell would need more ribosomes, so your comparison would be against the change in activity of the whole cell. Which I guess you may be interested in.
I would agree that 18S might not be the cleanest house keeping control.
I use the GETprime database of validated, exon-specific qPCR primers. Check out the link.

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.
