It is showed by authors that using of 8-para(toluenesulphonylamino)quinoline — a derivative of 8-oxyquinolin
result histochemical revealing by using of fluorescent microscopy of Zn+2-ions in cells of tissue of prostate,
in pancreatic B-cells and in salivary glands contains a large amounts of ions. This method is high sensitive
and high specific for revealing of Zn+2-ions and there are only one step of staining procedures. Meanwhile
it is possible to use only fresh frozen sections of tissues for investigation within short time limited by
15–20 min.
