SDS-PAGE analysis of the ternary GM-CSF receptor complex.
Mixtures of sβc, sGMRα, and either GM-CSF (A) or E21R (B) were analyzed by size-exclusion chromatography as described for Figure 2F and I. Fractions were collected at 1-minute intervals, fractionated by 12.5% SDS-PAGE under reducing conditions, and silver stained.33 The positions of individual components are indicated.
