Left: Analysis of 14.3.3 eta expression in HeLa cells by Immuncytochemistry using mouse antibody to 14.3.3 protein eta (red, 1:1,000). Blue: DAPI nuclear stain. The antibody reveals the diffuse cytoplasmic distribution of 14.3.3 protein with higher concentration in the perinuclear region. Right: Western blot analysis of whole brain lysates (lanes 2,3), and cell lysates (lanes 4-8), using mouse antibody to 14.3.3 eta (green, 1:5,000). [1] protein standard, [2] rat brain, [3] mouse brain, [4] NIH-3T3, [5] HEK293, [6] HeLa, [7] SH-SY5Y, [8] C6 cells. The strong band at 28 kDa corresponds to 14.3.3 eta protein.
