Hydrochloric acid for iron detection reaction 2% as in vitro diagnostic agent is specially designed to be used in histological staining of biological samples. Its main application is to enable the detection of iron deposition in tissues.

In its application, hydrochloric acid is not mixed directly with the sample, but is first mixed with potassium ferricyanide, resulting in Berlin Blue. This compound selectively binds to iron in the tissue samples and produces a bluish stain. The staining allows visualization of the iron-containing regions under the microscope, which allows precise quantification of the iron content in the samples.

The use of this hydrochloric acid solution is important in various areas of medical diagnostics and life science research. It can help to better understand iron metabolism in the body and provide information about possible disease states. The solution has proven to be a reliable and accurate reagent for Berlin Blue staining, successfully used in numerous medical laboratories and research institutions.
