Fig. 1From: Increasing temperature denatures canine IgG reducing its ability to inhibit heartworm antigen detectionChange in IgG antibody concentration following heating of antibody solutions (Ab1–4) at six temperatures as measured by total protein. Protein concentrations were significantly increased when heated at 75 °C and were significantly decreased for antibody solutions heated at 85 °C, 95 °C and 104 °CBack to article page
