Question

Which chemical used to attach dye in tissue

Answer 1

Explanation:

mordant

A mordant or dye fixative is a substance used to set (i.e. bind) dyes on fabrics by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in cell or tissue preparations.

Answer 2

Answer:

Haematoxylin and eosin staining is frequently used in histology to examine thin tissue sections. Haematoxylin stains cell nuclei blue, while eosin stains cytoplasm, connective tissue and other extracellular substances pink or red. Eosin is strongly absorbed by red blood cells, colouring them bright red.
