What are the chemicals called that are sometimes used to make specimens visible?

Chemicals such as dyes, stains, or fixatives are commonly used in specimen preparation to make them more visible under a microscope. Dyes bind to specific cellular components, stains highlight certain structures, and fixatives preserve the specimen's morphology for observation.


What leukocyte stains with acidic dyes?

Eosinophils are leukocytes that stain with acidic dyes such as eosin. They are involved in the immune response to allergic reactions and parasitic infections.


Could other dyes be used as a counterstain?

Yes, other dyes can be used as counterstains in histology and microbiology to enhance the contrast between the target tissue or cells and the background. Common counterstains include eosin, methylene blue, and hematoxylin, which are used in combination with primary stains like hematoxylin and eosin staining. Different counterstains can provide different color contrasts for better visualization under the microscope.


What dyes are used to stain ribosomes?

Ribosomes can be stained using various dyes, with the most common being methylene blue, which binds to RNA-rich regions. Other dyes include acridine orange and toluidine blue O, which also target nucleic acids. These stains help visualize ribosomes under a microscope, as they highlight the dense RNA content within these cellular structures.


What charge does a basic stain have?

A basic stain typically has a positive charge. This is because basic stains are usually composed of cationic (positively charged) dyes that can bind to negatively charged components of the cell, such as nucleic acids and certain proteins. This affinity allows basic stains to effectively color and highlight cellular structures during microscopy.

Difference between dye and stain?

Dyes are colored substances that chemically bond with the material they are applied to, giving it color without obscuring the underlying pattern or texture. Stains, on the other hand, are designed to penetrate the material and alter its color while allowing the underlying texture or pattern to remain visible. Stains are typically used for wood, while dyes are more commonly used on fabrics or plastics.

What are UGS dyes?

UGS dyes refer to "universal genomic DNA sequence dyes" used in molecular biology and genomics research. These dyes are usually fluorescent and commonly used for staining DNA in agarose gels or as a labeling reagent in various DNA assays, such as qPCR or DNA sequencing. UGS dyes help visualize and quantify DNA samples and are essential tools in molecular biology laboratories.

What stains are impossible to remove?

Some stains that are typically difficult to remove include ink, rust, and certain types of dyes. The removal of these stains may require specialized cleaning products or professional services.

What is basophilia?

Basophilia is the condition of being basophilic - describing biological tissue which stains readily with basic dyes.


What is the difference between paint pigments and dyes?

Paint pigments are solid particles that are mixed into a medium to give color, while dyes are liquids that are absorbed by materials to provide color. Pigments sit on the surface of a material, while dyes penetrate and become part of the material.
