The Rugged Terrain of Mouse Plasma

Researchers led by Fred Hutchinson's Sam Hanash have published a mouse plasma peptide atlas in Genome Biology. In it, they've identified 13,779 distinct peptides corresponding to about 3,000 proteins that are estimated to span a 7-logarithmic range of abundance in plasma. They say a major finding from this work is novel isoforms and transcript variants not previously predicted from genome analysis, and hope to use the atlas for disease research.
