Metanil Yellow 2% is a synthetic azo dye that has applications in various scientific fields. In particular, it is used to stain nucleic acids and polysaccharides and is known for the specific visualization of microorganisms such as bacteria and fungi in histology and medical diagnostics.

The particular suitability of Metanil Yellow 2 % results from its chemical properties, which enable it to selectively stain cell structures such as mucous substances and fungal structures. The high color intensity of the dye leads to well-differentiated staining and facilitates microscopic examination.

The functionality of Metanil Yellow 2 % is based on interactions between the dye and target molecules such as nucleic acids or polysaccharides. These interactions allow selective staining of the desired cell structures and facilitate identification and analysis under the microscope.

Another application of Metanil Yellow 2 % is in trichrome staining, where it can be used as a connective tissue stain as an alternative to light green and anilline blue. The use of Metanil Yellow in this method contributes to the differentiated visualization of cellular components and enables precise analysis of tissue samples in histology and medical diagnostics.
