NANOGP8 and cancer: Both 42 kD and 35 kD proteins could be immunoprecipitated down by the R&D goal pAb and detected on WB by the Kamiya pAb (Fig. 5B, lanes 5 and 6), which co-migrated with the endogenous Nanog1 proteins in NTERA2 NE (Fig. 5B, lane 12; see below for further discussions on NanogP8 in cancer cells).
