Western blot analyses of RXRα in D⁺ cells after incubation with G-CSF, ATRA, or G-CSF + ATRA.

Loading was standardized by equal cell numbers. Coomassie staining of a duplicate gel shows approximately equal amounts of protein in each lane. C indicates untreated control; G, G-CSF (10 ng/mL); R, ATRA (3 μmol/L); GR, G-CSF + ATRA treatment.
