Coimmunoprecipitation of RBP40 and psbD mRNA.
Chloroplast stromal proteins were used for immunoprecipitation reactions with an αRBP40 antiserum or the preimmune serum (PRE). RNAs were extracted from precipitates (αRBP40 and PRE) and supernatants (SαRBP40 and SPRE), and equal proportions were subjected to dot-blot hybridization using the radiolabeled DNA probes indicated at top.
