Western blot analysis of extracts from F9 cells and NTERA-2 cells, untreated (-) or treated with retinoic acid (1 μM, 5 d; +) to induce differentiation, using JARID2 (D6M9X) Rabbit mAb (upper) and GAPDH (D16H11) XP<sup>®</sup> Rabbit mAb #5174 (lower). As expected, JARID2 protein levels decrease upon NTERA-2 cell differentiation.
