(A) Western analysis for Hsp70 in supernatants of pcDNA3.1+Hsp70 and Renilla luciferase or mock-transfected TRAMP-C2 cells. Spent media were collected at 24, 48, and 72 h and concentrated as in Materials and methods. (B) Western analysis for Hsp70 in cell extracts of Hsp70, Renilla luciferase, and mock-transfected TRAMP-C2 cells. Ponseau S was used for normalisation. (C) Percent of Hsp70 in supernatants (Sup) and cell extracts (CE) of Hsp70 and mock-transfected TRAMP-C2 cells as determined by densitometry. (D). Comparison of luciferase activity in cell extracts (C) vs supernatants (S) in C2 cells transfected with pcDNA3.1+Hsp70 and Renilla luciferase at various time points. Spent media and whole-cell protein extracts were prepared as above. (E) Percentage of renilla protein was determined by luminescence.
