Fig. 5From: Increasing temperature denatures canine IgG reducing its ability to inhibit heartworm antigen detectionEffect of A pepsin digestion and B Tris[2-carboxyethyl] phosphine hydrochloride (TCEP) on antigen detection in pooled excretory/secretory (E/S) media from live heartworms as measured by DiroCHEK® via optical density at 650 nm. No significant changes to antigen detection among these E/S media were observedBack to article page
