Mouse_Hippocampus_LCMSMS_IEF_Pooling


ABSTRACT: Protein extract from a single mouse hippocampus was enzymatically digested and fractionated by isoelectric focusing. Aliquots of fractions were pooled to make fewer, more complex samples. The unfractionated lysate, fractions, and pooled fractions were subjected to liquid chromatography–mass spectrometry analysis. Samples consisting of many individual fractions had more protein identifications and quantified proteins with more spectral counts and greater precision than protein extract that was unfractionated or pooled into fewer LC-MS/MS samples.

An assessment of fractionated mouse hippocampal peptides was conducted. Protein extract from a single mouse hippocampus was enzymatically digested and fractionated by IEF. Aliquots of fractions were pooled into fewer, more complex samples. The unfractionated lysate, fractions, and pooled fractions were subjected to LC-MS/MS analysis.
