OriGene Technologies this week released 5,000 purified human proteins, the most comprehensive offering of human cell-produced human proteins, according to the Rockville, Md., firm.

The recombinant proteins are purified from HEK293 cells "transiently transfected with [Origene's] TrueORF cDNA clones," the company said in a statement. Proteins expressed by mammalian cells are superior to proteins from other expression systems because they have the "most authentic protein structure, post-translational modifications and functions," OriGene added.


The mzIdentML specifications for representing peptide and protein identifications have reached version 1.0 status, the Human Proteome Organizations Proteomics Standards Initiative Proteomics Informatics group confirmed this week. The main specifications are available here and as a direct download here. Several implementations are under development for exporting mzIdentML from the main proteomics search engines.
