Time course of heat shock protein 70.1 (Hsp70.1) protein expression in bovine peripheral blood mononuclear cells. Cells with --, C-, and CC genotypes (a) and with TT, GT, and GG genotypes (b) were subject to heat shock (43°C × 1 h) and then recovered at 39°C for 1, 2, 4, 8, 16, and 24 h. Aliquots of cells were analyzed for expression of Hsp70.1 proteins by ELISA at the indicated time points. Results are means ± SE of duplicate determinations. Different letters indicate differences for P < 0.05 between genotypes within time. NoHS no heat shock
