Method (Primary source abstract:) "Using measurements of absolute protein and mRNA abundances in cellular lysate from the human Daoy medulloblastoma cell line, [researchers] quantitatively evaluate the impact of mRNA concentration and sequence features implicated in translation and protein degradation on protein expression."
Comments "Two other systemwide estimates of protein abundance in mammalian cells are, like Schwanhausser et al.'s (2011), lower than [researchers']. These two reports suggest that the median abundance protein detected is present at 8,000 (primary source) or 9,700 (Beck et al., 2011) molecules per cell versus our estimate of 170,000 molecules per cell [BNID 110234]."
