Fig. 4. Immunocytochemistry (ICC) showing strong nuclear staining in Ad-TAp73 SH-SY5Y infected cells. (A) SH-SY5Y cells; (B) IGRN-91 cells. Parental cells (Uninfected), or cells infected with full-length p73
(Ad-p73
), with
Np73a (Ad-
Np73
) or with empty vector (Mock). In contrast to SH-SY5Y cells (A), ICC in IGR-N-91 cells led to a diffuse and faint staining in whole cells (B), regardless of the expressed p73 isoform. `Cont' represents control of second antibody.
