Comments concerning this interaction

Source was nuclear extract of S2 cell line; bait produced from endogenous gene; prey produced from endogenous gene.

(Collins et al., 1999)

Nuclear extract was fractionated on a glycerol gradient and fractions containing brm and osa were used for immunoprecipitation.
