Serotonin Genes

Revision as of 12:29, 19 November 2007 by Houpt (talk | contribs)

I am interested in 4 of the genes related to serotonin function in depression and food intake: Pet-1, Serotonin Transporter (5HTT), Tryptophan Hydroxylase 2 (TPH2), and 5HT2C Receptor (5HT2CR)

ISH probes

Pet-1

Reference:

Serotonin Transporter

Reference:


Tryptophan Hydroxylase 2

(see PCR primers below).

5HT2C Receptor

(see PCR primers below)

Was originally called the 5HT1C receptor when first discovered.
