The expression was detected by immunofluorescence (Ruiz-Avila et al., 1995; Kusakabe et al., 2000; Max et al., 2001; Shindo et al., 2008), in situ hybridization (Yang et al., 1999; Kusakabe et al., 2000; Kim et al., 2003; Shindo et al., 2008), PCR (Kusakabe et al., 1998; Tizzano et al., 2008), Southern (Kusakabe et al., 2000), and Northern blot (Kusakabe et al., 1998), as well as gene expression profiling (Huang et al., 1999).
