Figure 2. Assessment of Heat Shock Induction and Levels of Hsp90 Inhibition.
(A) Western blots to assess Hsp70 induction following overnight treatment of WT embryos initiated at 50% epiboly with increasing concentrations of radicicol or 17AAG. As positive control, Hsp70 was induced by incubating embryos at 37 °C for 30–60 min before harvesting.
(B) Western blots showing graded reduction in RAF1, an Hsp90 client-protein, in response to inhibition by radicicol and 17AAG.
(C) Western blots to assess Hsp90, Hsp70, and RAF1 levels in embryos injected with 6 ng of universal morpholino control (STD MO) or Hsp90 a+b morpholinos at the indicated individual amounts. α-tubulin was used as loading control.
