Figure 1From: Sequential association of myogenic regulatory factors and E proteins at muscle-specific genesExpression of myogenic regulatory factors (MRFs) and E proteins over a time course of differentiation in C 2 C 12 cells. C2C12 cells were differentiated for the indicated number of days and harvested for protein (UD, undifferentiated cells; D1-D10, cells differentiated for the indicated number of days). Protein concentration was determined for each extract and used to normalize the sample loading. Parallel blots were probed for each of the indicated antibodies as described in Methods.Back to article page
