|Title:||The Benzidine Technique For Histochemical Detection Of The So4 Ion|
Da Cruz-Hoefling M.A.
|Abstract:||The benzidine technique for histochemical detection of the SO4 ion was studied analytically on filter paper strips loaded with 0.02 ml of solutions of sulfate containing and sulfate free substances. The influence of the benzidine solution pH on the SO4 and PO4 ion precipitation was analyzed and the experimental condition where the SO4 ion was specifically precipitated was established. On the basis of this study a benzidine histochemical technique suitable to detect the SO4 ion without interference of the PO4 ion was proposed for tissue sections. This technique has some advantages over the other benzidine techniques previously proposed mainly concerning its specificity.|
