Anti-Hsp70 antibody levels in the serum of patients before, and at indicated time-points after radiation therapy. Time course of anti-Hsp70 antibodies in the serum of patients with SCCHN tumors before and after therapy. Blood was collected and anti-Hsp70 antibodies were determined by anti-Hsp70 antibody ELISA. Standard box plots are shown with boundaries indicating the 25^th and the 75^th percentile. The line inside boxes indicates the median and the whiskers indicate the 10^th and 90^th percentile, respectively. All outliers are shown in the graph. (healthy n = 4, patients before therapy n = 16, patients after therapy at least 6 weeks after radiation therapy n = 6).
