Proteome Dataset for Adult-derived Mouse Microglia


ABSTRACT: We report methods development for quantitative proteomic analysis of samples with limited number of cells. The improvements include suspension trapping (S-Trap) for sample processing, longer analytical column length (75cm), and a segmented data dependent acquisition approach. The modified approach was applied to the proteomic analysis of adult-derived mouse microglia and optimized to the cell count expected from mouse brain (~300K microglial cells). With the improved approach, over 4500 quantifiable proteins can be obtained (in biological triplicate) with an average CV of 10%.

Microglia, as the resident brain immune cells, can exhibit a broad range of activation phenotypes, which have been implicated in a multitude of central nervous system disorders. Current widely studied microglial cell lines are mainly derived from neonatal rodent brain that can limit their relevance to homeostatic function and disease-related neuroimmune responses in the adult brain. Recently, an adult mouse brain-derived microglial cell line has been established; however, a comprehensive proteom  ...[more]
