I was wondering how can we make a theoretical human proteome quantify profile? Is it possible to do it? I mean there is a paper from Gygi SP (http://www.ncbi.nlm.nih.gov/pubmed?t...%202000%20PNAS) where they used Codon bias to evalute 2-DE. However, codon bias can not be used on human. There is emPAI (http://www.ncbi.nlm.nih.gov/pubmed?t...n%202005%20MCP) introduce by Mann. Here you need to have experiment data also. Is there software where we can give the human proteome database such as UniProtKB/Swiis-Prot and give us some index for abundancy of proteins?
