codon optimization for CHO cells - (May/21/2014 )

Hi

I am trying to express a human gene in CHO cells, I am going to order gene synthesis but brfore that I want to optimiza the codon usage for CHO cells. I was wondering how I can find a confirmed reference table with preferred codons for particular organisms?
