Immunostaining of primary rat cortical neuroepithelial cells with O5990-02C (red, 1:1000). The cells were treated with basic FGF for 30 hours prior to staining (this induces Olig2 expression in these primary cells).

Immunostaining of Olig 2 in 3-month-old mouse brain using O5990-02C: Red; Nuclear: Blue.
