Figure 1. Effect of heat shock on native CSPα expression.

(A) CAD cells were treated with or without 200 µM quercetin for 24 hours followed by heat shock for 40 min at 42°C and allowed to recover for 5 hours. 30 µg of protein was resolved by SDS-PAGE. CSPα, Hsp70 and Hsp40 were detected by Western analysis. (B) Quantification of CSPα. Data were derived from a total of 8 separate experiments.
