Proteome profile of the mature rat olfactory bulb.

Olfactory bulbs (OBs) are one of the few brain areas, which show active neurogenesis and neuronal migration processes in adult rats. We constructed a proteome map of the 21 days old rat OBs and identified total 196 proteins, out of which 76 proteins were not reported earlier from rat brain. This includes 24 neuronal activity-specific proteins present at high levels, 7 of which are reported for the first time from OBs.
